    • seasonal influenza prophylaxis

    General Dosing Information

    • The Advisory Committee on Immunization Practices (ACIP) and the American Academy of Pediatrics (AAP) recommend annual flu vaccination with an age-appropriate influenza vaccine, without preference of 1 product or formulation over another, for everyone 6 months and older.[63436][63520] The inactivated influenza vaccine (IIV4) or quadrivalent recombinant influenza vaccine (RIV4) should be used instead of the quadrivalent live attenuated influenza vaccine (LAIV4) for vaccination in patients with immunocompromising conditions, including those caused by medication, congenital or acquired immunodeficiency, HIV infection, and anatomical or functional asplenia. Additionally, the LAIV4 vaccine should not be used in pregnancy, close contacts and caregivers of severely immunocompromised persons in a protected environment, anyone with a severe allergic reaction to any component of the vaccine, patients with cranial cerebrospinal fluid leak or cochlear implant, pediatric patients receiving concomitant aspirin or salicylate-containing medications, and children 2 to 4 years of age with a history of asthma or wheezing.[53026][63436]
    • Children 6 months through 8 years of age require 2 vaccinations (given at least 4 weeks apart) during the first flu season in which they are immunized to maximize immune response. ACIP recommends that children aged 6 months through 8 years who have previously received at least 2 doses of trivalent or quadrivalent influenza vaccine before the beginning of the influenza season receive only 1 dose for the current influenza season. The 2 previous doses need not have been given during the same season or consecutive seasons.[63436]
    • For patients 65 years and older, higher dose or adjuvanted influenza vaccines are preferred to the standard dose, unadjuvanted, inactivated influenza vaccines. Higher dose vaccines contain a higher dose of hemagglutinin antigen per virus than standard-dose vaccines (45 to 60 mcg compared to 15 mcg for standard-dose vaccines). The adjuvanted, inactivated influenza vaccine contains MF59 adjuvant. If these vaccines are not available for administration, then any other age-appropriate influenza vaccine should be used.[63436]
    • Ideally, the influenza vaccine should be given by the end of October in the United States, but vaccination during flu season can occur at anytime. Pregnant individuals should receive the inactivated or recombinant influenza vaccine as soon as it becomes available. It is safe and effective to administer other non-virus containing or inactivated vaccines (Tdap, RSV, or Covid-19 vaccine) during the same visit.[70419]
    • For nonpregnant adults, avoid vaccination in July and August unless later vaccination may not be possible. Children requiring 2 vaccinations should receive their first dose as soon as possible after the vaccine is available to allow the second dose to be received by the end of October. The optimal time for organized vaccination programs for persons at high risk for influenza-related medical complications is usually during October to November; administration closer to the time of flu season lessens the risk of antibody decline during the month's coverage is most needed. However, vaccination may occur earlier to avoid missing opportunities to immunize susceptible individuals. Full immune response requires only 2 weeks, so even as the influenza season progresses through February, patients may still receive immunization and its benefits.[63436]
    • NOTE: The 2024/2025 trivalent inactivated vaccine virus strains for egg-based vaccines are an A/Victoria/4897/2022 (H1N1) pdm09-like virus, an A/Thailand/8/2022 (H3N2)-like virus, and a B/Austria/1359417/2021 (B/Victoria lineage)-like virus. The trivalent formulation of cell- or recombinant-based influenza vaccines are an A/Wisconsin/67/2022 (H1N1) pdm09-like virus, an A/Massachusetts/18/2022 (H3N2)-like virus, and a B/Austria/1359417/2021 (B/Victoria lineage)-like virus. The 2024/2025 vaccine available in the United States is a trivalent vaccine. For distribution to countries outside the United States that cannot revert to trivalent seasonal influenza vaccine as quickly, the inclusion of a second B strain, a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus, is recommended for quadrivalent egg-, cell-, or recombinant-based vaccines.[65686]
    • Updates for coronavirus disease 2019 (COVID-19):
      • The influenza season will coincide with the continued or recurrent circulation of SARS-CoV-2. Influenza vaccination of patients 6 months and older may reduce symptoms that might be confused with those of COVID-19. Additionally, prevention and reduction of influenza severity could decrease hospitalizations and intensive care unit admissions and alleviate stress on the health care system.[63436]
      • The COVID-19 vaccine may be administered with other vaccines without regard to timing. When deciding whether to coadminister another vaccine with COVID-19 vaccines, consider if the patient is behind or at risk of becoming behind on recommended vaccines, their risk of vaccine-preventable disease, and the reactogenicity profile of the vaccines. If multiple vaccines are given at a single visit, administer each injection in a different injection site; separate injection sites by 1 inch or more, if possible. Administer the COVID-19 vaccines and vaccines that may be more likely to cause a local reaction (e.g., adjuvanted vaccines) in different limbs, if possible.[66175]

      Description/Classification

      Description

      NOTE: The 2024/2025 trivalent inactivated vaccine virus strains for egg-based vaccines are an A/Victoria/4897/2022 (H1N1) pdm09-like virus, an A/Thailand/8/2022 (H3N2)-like virus, and a B/Austria/1359417/2021 (B/Victoria lineage)-like virus. The trivalent formulation of cell- or recombinant-based influenza vaccines are an A/Wisconsin/67/2022 (H1N1) pdm09-like virus, an A/Massachusetts/18/2022 (H3N2)-like virus, and a B/Austria/1359417/2021 (B/Victoria lineage)-like virus. The 2024/2025 vaccine available in the United States is a trivalent vaccine. For distribution to countries outside the United States that cannot revert to trivalent seasonal influenza vaccine as quickly, the inclusion of a second B strain, a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus, is recommended for quadrivalent egg-, cell-, or recombinant-based vaccines.[65686]

       

      Inactivated influenza virus vaccine (IIV) is used to confer immunity against specific strains of influenza virus. Most IIV products consist of inactivated virus particles prepared from the allantoic fluid of chick embryos inoculated with the influenza virus; however, some egg-free products are now available. Flucelvax employs mammalian cells (Madin-Darby canine kidney epithelial cells) rather than chicken embryos to prepare the inactivated virus particles.[60831] Flublok uses baculovirus (Autographa californica nuclear polyhedrosis virus) infected insect cells (fall armyworm) to produce recombinant influenza virus hemagglutinin (HA) proteins.[61294] Because influenza viruses are continually changing and antibodies produced by the host in response to the vaccine diminish over time, annual immunization is required. The parenteral influenza vaccines contain either 3 (2 type A and 1 type B) or 4 (2 type A and 2 type B) strains that represent the influenza viruses likely to circulate during the annual flu season. The US and Canadian governments (individually) determine annually which strains to include in the vaccine based on epidemiological studies and consultation with several groups, including the World Health Organization.[63436] The Advisory Committee on Immunization Practices (ACIP) and the American Academy of Pediatrics (AAP) recommend annual flu vaccination with an age-appropriate influenza vaccine, without preference of 1 product or formulation over another, for everyone 6 months and older.[63436][63520]

       

      Updates for coronavirus disease 2019 (COVID-19):

      The influenza season will coincide with the continued or recurrent circulation of SARS-CoV-2. Influenza vaccination of patients 6 months and older may reduce symptoms that might be confused with those of COVID-19. Additionally, prevention and reduction of influenza severity could decrease hospitalizations and intensive care unit admissions and alleviate stress on the health care system.[63436]

      Administration Information

      General Administration Information

      For storage information, see the specific product information within the How supplied section.

      • The healthcare professional should have immediate availability of epinephrine injection and other agents used in the treatment of anaphylaxis in the event of a serious allergic reaction.
      • Inform the parent, guardian, or responsible adult of the benefits and risks of the vaccine. Provide the Vaccine Information Statements from the manufacturer to the parent or guardian before each immunization. This action is required by the National Childhood Vaccine Injury Act of 1986.
      • Record the manufacturer, lot number, administration date, and the name and address of the person administering the vaccine in the patient's permanent record. These actions are required by the National Childhood Vaccine Injury Act of 1986.[52653]
      • Complete a Vaccine Adverse Event Reporting System (VAERS) report form if an adverse event occurs. The reporting of events is required by the National Childhood Vaccine Injury Act of 1986. The toll-free number for VAERS is 1-800-822-7967. Depending on the adverse reaction, subsequent vaccination, if needed, may be contraindicated.

      Route-Specific Administration

      Injectable Administration

      • Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit.
      • Do not mix with any other vaccine.
      • When concomitant administration of other vaccines is required, they should be given with different syringes and at different injection sites.[43236]

      Intramuscular Administration

      • Before administration, clean skin over the injection site with a suitable cleansing agent.
      • For products supplied as a suspension, shake well immediately before use.
      • For vials, use a sterile syringe and needle to withdraw vaccine from vial. It is recommended that small syringes (0.5 mL) be used to minimize product loss. For prefilled syringes, attach a sterile needle.[61129]
      • Inject into the anterolateral aspect of the mid-thigh (for infants younger than 1 year of age) or the deltoid muscle of the upper arm (for children and adults). Do NOT administer in the gluteal muscle.[61129][65107]
      • Doses from Afluria vials may be administered to adults (18 to 64 years) using the PharmaJet Stratis needle-free injection system. This spring-loaded device delivers a single IM dose by creating a narrow fluid stream that rapidly penetrates the skin. Safety and efficacy of needless injectors have not been established in older adults (older than 64 years) nor pediatric (less than 18 years) patients.[61129]
      • Storage of opened vials: Acceptable storage varies depending on vaccine formulation and brand. See How Supplied section or directly contact the manufacturer for specific vaccine being used.

      Other Injectable Administration

      Intradermal administration (Fluzone Intradermal only):

      • Gently shake the device and remove the needle cap.
      • Insert the needle perpendicular to the skin in the region of the deltoid. Maintain light pressure on the surface of the skin and push the plunger to inject the dose. Do not aspirate.
      • After needle removal from the skin, firmly push the plunger to activate the needle shield.[51850][58656]

        Adverse reactions associated with administration of the influenza virus vaccine are usually mild and are more likely to occur in children than in adults. The most common adverse reaction occurring after influenza virus vaccine is an injection site reaction that can manifest as pain (more than 1%), erythema (more than 1%), tenderness (21% to 77.9%), induration (0.5% to 17.7%), swelling (0.5% to 56.8%), pruritus (0.2% to 46.9%), or ecchymosis (0.5% to 17%).[52652] [54943] [55717] [60831] [61129] [61294] [64726] [65035] Extensive swelling of the injected limb has been reported with postmarketing use of Flucelvax.[60831] In older adults, 23% reported some type of injection site reaction as compared with 14% of those given placebo. This study also revealed that reactions were more frequent in women than men, although the reason for this was unclear.[23572] Among adults who received Afluria vaccine, 36% to 69% had local tenderness, 15% to 48% had pain, 3% to 16% had erythema (redness), 4% to 9% had swelling, and 5% or less had bruising at the injection site. Of the adults (18 to 64 years) administered Afluria via the PharmaJet Stratis needle-free injection system, 89% had local tenderness, 65% had swelling, 64% had pain, 60% had erythema (redness), 28% had pruritus, and 18% had bruising. In studies including pediatric patients (5 to 17 years of age) receiving Alfuria, 36% to 68% had pain, 10% to 24% had erythema (redness), 8% to 17% had induration, and 13% to 17% had swelling. In children 6 to 59 months of age, pain (20.8% to 35.5%), redness (20.8% to 22.4%), and swelling/lump (6.1% to 10.1%) were the most frequently reported injection site reactions.[61129] Local injection site reactions occurred in more patients at least 65 years of age after Fluzone High-Dose than after Fluzone. For example, pain was reported in 36.4% to 41.3% of the Fluzone High-Dose and Fluzone Quadrivalent High-Dose recipients whereas 32.6% of Fluzone recipients experienced pain. Further, erythema and swelling were experienced more frequently in the Fluzone High-Dose and Fluzone Quadrivalent High-Dose (5.7% to 6.2% and 4.7% to 4.9%) compared to Fluzone recipients (2.7% and 1.8%).[54943] [58656] [64726] In pediatric patients 6 months to 8 years receiving Fluzone, 57% to 66% had pain, 47.3% to 54.1% had tenderness, 23.1% to 37.3% had erythema, and 12.9% to 24.8% had swelling.[54943] Adverse local reactions typically persist for up to 2 days.

        Systemic adverse reactions such as malaise (1% to 38.1%), drowsiness (13% to 37.7%), fever (0% to 16%), diaphoresis (1% to 10%), arthralgia (0.3% to 15%), chills (2% to 7.3%), shivering (2.6% to 12.1%), fatigue (1% to 20%), headache (1% to 26%), and/or myalgia (1% to 35.5%) can occur after administration of the influenza virus vaccine.[30823] [41685] [41686] [47301] [52652] [54943] [55717] [58656] [60831] [61129] Of the adults (18 to 64 years) administered Afluria via the PharmaJet Stratis needle-free injection system, 36% had myalgia, 31% had malaise, 25% had headache, 7% had chills, and 0% had fever.[61129] These reactions generally begin 6 to 12 hours after administration of the vaccine and persist for 1 to 2 days. Children who have not been previously exposed to influenza virus are more likely to experience these reactions, especially if administered the whole-virus vaccine. It is recommended that children receive the split-virus (subvirion) vaccines instead of whole-virus immunizations. In fact, placebo-controlled trials suggest that among older adults and healthy young adults, split-virus influenza vaccine is not associated with higher rates of systemic symptoms than placebo injections. More patients at least 65 years of age who received Fluzone High-Dose as compared with Fluzone had systemic adverse reactions. For example, among Fluzone High-Dose and Fluzone Quadrivalent High-Dose recipients, 18.9% to 22.7% had myalgia, 13.2% to 18% had malaise, 14.4% to 16.8% had headache, 4.7% to 5.4% had shivering, and 0.4% to 3.6% had fever whereas among 1,260 Fluzone recipients, 18.3% had myalgia, 14% had malaise, 14.4% had headache, and 2.3% had fever.[30823] [64726] Similarly, more patients at least 65 years of age who received Fluad as compared with Agriflu had systemic adverse reactions. Older adults receiving Fluad experienced myalgia (14.7% vs. 9.7% Agriflu), fatigue (13.3% vs. 10.4% Agriflu), headache (13.2% vs. 11.2% Agriflu), arthralgia (8.5% vs. 7.8% Agriflu), and chills (6.7% vs. 4.7% Agriflu).[60361] Irritability (1.7% to 32.9%), malaise and fatigue (1% to 14.3%), myalgia (9.9%), headache (6.2%), and fever (3.7% to 7.2%) were reported in pediatric patients 6 to 59 months of age after receiving Afluria. Irritability was reported in 16% to 21% of pediatric patients after receiving Fluarix.[41685] [52652] Irritability (34.9% to 54%) and abnormal crying (18.6% to 41.2%) were also reported in pediatric patients 6 to 36 months of age after receiving Fluzone.[30823] [54943] Migraine was reported in 1% of adult patients after receiving Fluarix.[41685] Chills, asthenia, and abnormal gait have been observed during postmarketing surveillance.[41686] [47301]

        Rarely, immediate allergic reactions occur after inactivated influenza vaccine administration. An allergic reaction may present as urticaria, angioedema, bronchospasm, or anaphylactoid reactions including anaphylaxis or anaphylactic shock; these reactions are most likely the result of hypersensitivity to residual egg protein. In 4 clinical trials of trivalent inactivated influenza vaccine with more than 10,000 subjects, 1 case of anaphylaxis occurred.[52652] Erythema multiforme, rash, vesicular rash, maculopapular rash, pruritus, serum sickness, and Stevens-Johnson syndrome have been reported with inactivated influenza vaccine through postmarketing surveillance.[30823] [41685] [41686] [47301] [61129]

        An increased risk of developing the Guillain-Barre syndrome (GBS) after administration of the inactivated influenza virus vaccine was evident in 1976. Subsequent influenza vaccinations during the next few years were not associated with this increased risk. However, during 1993 to 1994 twice the average yearly rate (for the period 1990 to 1995) of influenza vaccine-associated incidences of GBS were reported, representing a risk of slightly more than 1 additional case of GBS per million persons vaccinated. In most cases, symptoms were limited and reversible, but fatalities have occurred. Persons with a history of GBS have a substantially greater likelihood of subsequently developing GBS than persons without such a history. Thus, the likelihood of coincidentally developing GBS after influenza vaccination is expected to be greater among persons with a history of GBS than among persons with no history of this syndrome. It is not known if influenza vaccination is causally associated with this risk for recurrence of GBS.[30823] [41685] [41686] [47301] [52652] [55717] [61129]

        Neurological disorders temporally associated with influenza vaccination, such as encephalopathy, optic neuritis/neuropathy, partial facial muscle paralysis, and neuropathic pain in the area of the brachial plexus, have been reported. Use of injectable vaccines has also been associated with cases of syncope and presyncope accompanied by transient neurologic events, such as visual disturbances, paresthesias, and tonic-clonic limb movements. Hypoesthesia, hypokinesia, abnormal gait, tremor, myelitis (including encephalomyelitis and transverse myelitis), confusion, dizziness, vertigo, insomnia, and neuralgia have been reported with influenza virus vaccine in postmarketing surveillance.[52652] [55717] [60831] [61129]

        Microscopic polyangiitis and vasculitis, including vasculitis which may be associated with transient renal involvement, have been reported with postmarketing experience using influenza virus vaccine.[30823] [41685] [41686] [47301] [52652] [60361] [61129]

        Febrile seizures have been temporally associated with administration of the inactivated influenza vaccine (IIV). As of December 13, 2010, there were 53 confirmed VAERS reports of febrile seizures in children 6 to 23 months of age after receiving any 2010 to 2011 IIV; 42 of these cases occurred after vaccination with Fluzone (trivalent IIV). The majority of seizures (32 of the 42) were classified as non-serious, and all patients recovered. Of the 42 reports, 36 occurred on the same day or the day after vaccination (median time between vaccination and seizure onset was 10 hours), and 27 received Fluzone at the same time as other vaccines. The elevation in temperature ranged from 100.4 to 104 degrees F.[43210] Over a 3 year period from 2003 to 2006, 35 seizures were reported after influenza vaccination. Seizures occurred in the presence of fever in 21 of the 35 reports, and 29 of the 35 occurred within 2 weeks of vaccination. Five of the 35 seizures occurred in patients with a history of prior seizures.[43209] During the 2006 to 2007 through 2010 to 2011 influenza seasons, increases in reports of febrile seizures occurred in children 6 months to 23 months of age receiving the IIV and PCV7, PCV13, or DTaP-containing vaccines. During the 2014 to 2015 season, administration of IIV with PCV13 also resulted in an increased risk for febrile seizures within days 0 to 1 after vaccine co-administration. Although this observational data may suggest association of the seizure with the simultaneous administration of the vaccines, immunization should not be delayed (e.g., by separating administration across multiple healthcare visits) due to the threat of disease.[47234] [63436] Convulsions (including febrile seizures) have been reported during postmarketing experience.[61129]

        Respiratory adverse reactions that have occurred after administration of influenza virus vaccine include rhinitis (1% to 10%), rhinorrhea (2.7% to 11.2%), nasal congestion (1% to 7%), otitis media (1.6% to 2.4%), nasopharyngitis (1.7% to 5%), infectious croup (1.4%), influenza-like illness (1% to 1.6%), cough (more than 1%), sore throat (more than 1%), upper respiratory tract infection (more than 1%), pharyngitis (more than 1%), oropharyngeal pain (more than 1%), and wheezing (1%).[30823] [41685] [41686] [47301] [52652] [55717] [61129] Dyspnea, dysphonia, stridor, respiratory distress, laryngitis, and asthma have been reported with influenza virus vaccine through postmarketing surveillance.[41685] [52652] [55717]

        Gastrointestinal adverse reactions that have occurred after administration of influenza virus vaccine include anorexia (loss of appetite) (1% to 32.3%), vomiting (1.4% to 14.8%), nausea (0.4% to 12%), change in eating habits (10% to 17.4%), upper abdominal pain (1.4%), and diarrhea (1% to 24.2%).[30823] [41685] [41686] [47301] [52652] [54943] [55717] [60361] [60831] [61129] Dysphagia has been reported with influenza virus vaccine in postmarketing surveillance.[55717]

        Neck pain (1% to 10%), dysmenorrhea (1.3%), back pain (1.5%), and pain in extremity (1.2%) have been reported in adults after administration of influenza virus vaccine (Fluarix).[41685] [52652] Arthritis and muscle weakness have been reported with influenza virus vaccine through postmarketing surveillance.[55717]

        Thrombocytopenia and lymphadenopathy have been reported with influenza virus vaccine through postmarketing surveillance.[30823] [41686] [55717] [61129]

        Red eyes (4% to 7%) have been reported in adult patients after administration of inactivated influenza vaccine. Conjunctivitis, photophobia, ocular pain, ocular inflammation and eyelid swelling, eye irritation, and conjunctival hyperemia have been reported with influenza virus vaccine through postmarketing surveillance.[41685] [47301]

        Chest pain (unspecified), sinus tachycardia, pallor, and flushing have been reported with influenza virus vaccine in postmarketing surveillance.[52652] [55717] [60831]

        Prior to administration, inform the parent, guardian, or responsible adult of the benefits and risks of the vaccine, and provide the Vaccine Information Statement, accessible at the Centers for Disease Control and Prevention (CDC) website. These actions are required by the National Childhood Vaccine Injury Act of 1986.[52653] If a dose of influenza virus vaccine, inactivated has been previously given, question the parent or guardian about previous adverse reactions that may preclude further administration. Report all adverse reactions to the Vaccine Adverse Event Reporting System (VAERS), as well as the manufacturer. The toll-free number for VAERS is 1-800-822-7967. Educate the responsible adult(s) to promptly report any adverse reaction after vaccine administration to a health care provider.[30823]

        Influenza virus vaccine should not be given via intravenous administration or subcutaneous administration, it is for intramuscular (IM) administration only, with the exception of the intradermal Fluzone products. All other formulations should not be given by intradermal administration.[52652] [54943] [55717] [60831] [61129] [61294] [64726] [65035] Incorrect administration may result in inadequate immunity.

        The decision to administer or to delay vaccination with the influenza virus vaccine because of current or recent febrile illness depends on the severity of symptoms and on the etiology of the disease. Consider delaying vaccinations during the course of a moderate or severe acute illness with or without fever and administer after the acute phase of illness has resolved. All vaccines can be administered to persons with mild illnesses. Persons with moderate or severe febrile illness should be vaccinated as soon as they have recovered from the acute phase of the illness.[65107]

        All inactivated influenza vaccines (IIVs), with the exception of Flucelvax and Flublok, are contraindicated in persons with a known history of a severe allergic reaction (e.g., anaphylaxis) to the vaccine or any of its components or persons who have had a life-threatening reaction to any previous influenza vaccination.[51849] [52652] [54943] [55717] [61129] [63436] [65035] Most of the vaccines available are contraindicated by the manufacturers in patients with egg hypersensitivity because these vaccines are prepared using embryonated chicken eggs. These vaccines contain only minimal amounts of egg protein; however, anaphylactic reactions can occur in individuals with severe egg allergies.[52652] [54943] [55717] [60831] [61129] Due to differences in manufacturing processes, Flucelvax and Flublok do not use eggs to propagate the virus; thus, they are only contraindicated in persons with a known history of a severe allergic reaction (e.g., anaphylaxis) to the vaccine or any of its components.[60831] [61294] Flucelvax, however, cannot be considered 100% egg-free because the initial seed virus is created using reference virus stains from the World Health Organization, which have been passaged in eggs. For patients with a history of severe allergic reaction (e.g. anaphylaxis) to an influenza vaccine, the Advisory Committee on Immunization Practices (ACIP) has specific recommendations for vaccine receipt. A history of a severe allergic reaction to a previous dose of any influenza vaccine (i.e., any egg-based IIV, cell culture-based IIV (ccIIV, Flucelvax), recombinant influenza vaccine (RIV, Flublok), or live-attenuated influenza vaccine (LAIV) of any valency) is a contraindication to future receipt of all egg-based IIV4s and LAIV4. A history of a severe allergic reaction to any egg-based IIV, RIV, or LAIV is a precaution for the use of ccIIV4. If ccIIV4 is administered, administer vaccine in an inpatient or outpatient medical setting and under supervision of a health care provider able to recognize and manage severe allergic reactions. A history of severe allergic reaction to any cIIV or component of ccIIV4 is a contraindication to future receipt of ccIIV4. A history of a severe allergic reaction to any egg-based IIV, ccIIV, or LAIV is a precaution for the use of RIV4. If RIV4 is administered, administer vaccine in an inpatient or outpatient medical setting and under supervision of a health care provider able to recognize and manage severe allergic reactions. A history of a severe allergic reaction to any RIV or component of RIV4 is a contraindication to future receipt of RIV4.[63436] The American Academy of Pediatrics (AAP), the ACIP, the American Academy of Allergy, Asthma, and Immunology (AAAAI), and the American College of Allergy, Asthma, and Immunology (ACAAI) do not recommend any special precautions for egg-allergic recipients, regardless of severity. Special precautions (i.e., special observation periods or administration in a specialized medical setting) are considered unnecessary due to the extremely rare risk of anaphylactic reactions after vaccination. They recommend that providers and screening questionnaires not ask about the egg allergy status of the influenza virus vaccine recipient.[62809] [63436] [63520] As with any biologic product, the prescriber or health care professional should have procedures in place to manage allergic reactions. The health care professional should have immediate availability of epinephrine (1 mg/mL) injection and other agents used in the treatment of severe anaphylaxis in the event of a serious allergic reaction to the influenza virus vaccine.[51849] [52652] [54943] [55717] [60831] [61129] [61294] [65035]

        Carefully consider the potential benefits and risks of the inactivated influenza vaccine (IIV) for patients who have developed Guillain-Barre syndrome (GBS) within 6 weeks of a previous influenza vaccination.[60831] Influenza immunization is generally not recommended in patients who have developed GBS within 6 weeks of a previous influenza vaccination. However, for most persons with a history of GBS who are at high risk for severe complications from influenza, many experts believe the benefits of the influenza virus vaccine justify yearly vaccination.[53026] [63436] [65107]

        For geriatric patients 65 years and older, higher dose or adjuvanted influenza vaccines are preferred to the standard dose, unadjuvanted, inactivated influenza vaccines. Higher dose vaccines contain a higher dose of hemagglutinin antigen per virus than standard-dose vaccines (45 to 60 mcg compared to 15 mcg for standard-dose vaccines). The adjuvanted, inactivated influenza vaccine contains MF59 adjuvant. If these vaccines are not available for administration, then any other age-appropriate influenza vaccine should be used.[63436]

        No adequate and well-controlled studies have been conducted in pregnant individuals. Based on available data from pregnancy registries of Flucelvax and Fluarix administered during pregnancy, there was no evidence of vaccine-associated risk of major birth defects or miscarriage. Data from a Pregnancy Exposure Registry in the U.S. looked at individuals vaccinated with Afluria quadrivalent vaccine during the influenza season 2017 to 2018 through 2020 to 2021. Of 483 pregnancies, 477 resulted in live births with 485 infants born. There were 2 stillbirths, neither with major birth defects (1 patient was vaccinated in the first trimester and 1 patient was vaccinated during the second trimester). There were 160 patients vaccinated before 20 weeks gestation, in these patients there were 4 spontaneous abortions (2.5%). Among the 171 patients vaccinated in the first trimester, there were 2 major birth defects (1.2%). In the 201 patients vaccinated in the second trimester, there were 2 major birth defects (1%). The data generated from this registry demonstrates rates of miscarriage and major birth defects that are consistent with the estimated background rates.[61129] During animal studies, no evidence of impaired fertility or fetal harm was noted with influenza vaccines. Pregnancy may increase the risk of serious medical complications from influenza. Therefore, the Advisory Committee on Immunization Practices (ACIP) recommends that all individuals who are or will be pregnant (in any trimester) during the influenza season be routinely vaccinated with an inactivated influenza vaccine (vs. live-attenuated influenza vaccine).[52652] [60831] [63436] The American College of Obstetricians and Gynecologist (ACOG) committee also recommends pregnant individuals receive the inactivated or recombinant influenza vaccine as soon as it becomes available. Ideally, the influenza vaccine should be given by the end of October in the United States, but vaccination during flu season can occur at anytime. It is safe and effective to administer other non-virus containing or inactive vaccines (Tdap, RSV, or Covid-19 vaccine) during the same visit.[70419] In addition to benefits to the mother, influenza vaccine administration during pregnancy appears to help protect newborns and infants. Fewer cases of laboratory-confirmed influenza occurred during the first 6 months of life among infants of the 159 mothers who received the inactivated influenza vaccine (6 cases) as compared with infants of 157 mothers who received the pneumococcal polysaccharide vaccine (16 cases). Some manufacturers have established pregnancy registries to monitor pregnancy outcomes and newborn health after vaccination. Patients who receive these vaccines during pregnancy are encouraged to enroll in these registries. For Sanofi Pasteur influenza vaccines (e.g., Fluzone and Flublok), patients are encouraged to contact Sanofi Pasteur at 800-822-2463.[52652] [54943] [55717] [60831] [61129] [61294] [64726] [65035]

        Data are limited regarding use of the influenza virus vaccine during breast-feeding, and its excretion in human breast milk is unknown. The Advisory Committee on Immunization Practices (ACIP) and the American Academy of Pediatrics (AAP) state inactivated virus vaccines pose no risk for mothers or their infants. Additionally, breast-feeding does not adversely affect immunization; limited data suggest breast-feeding may enhance the immune response to certain vaccine antigens. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally administered drug, health care providers are encouraged to report the adverse effect to the FDA.[52652] [54943] [55717] [60831] [61129] [61294] [63436] [64726] [65035] [65107]

        Patients with thrombocytopenia or a coagulopathy (e.g., hemophilia), vitamin K deficiency, or who are on anticoagulant therapy should be monitored closely when given influenza virus vaccine because bleeding can occur at the IM injection site.[65107]

        Although patients with human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS) may have a diminished immune response, influenza incidence and severity is higher in this patient population; therefore, administer the influenza virus vaccine according to the routine vaccine schedule.[65107]

        Injectable vaccines, including influenza virus vaccine, have been associated with episodes of syncope and fainting. These events may be accompanied by transient tonic-clonic limb movements, visual disturbances, and paresthesias. Prior to administration, ensure procedures are in place to prevent falls and restore cerebral perfusion. Monitor vaccine recipients after administration of the dose. If syncope occurs, place the patient in a supine or Trendelenburg position to restore cerebral perfusion.[60831]

        Although the influenza virus vaccine may be less effective in patients with significant immunosuppression, influenza incidence and severity is higher in this patient population; therefore, vaccination with the influenza virus vaccine is recommended for these patients. Patients with primary immunodeficiency includes patients with severe combined immunodeficiency (SCID), hypogammaglobulinemia, or agammaglobulinemia. The effectiveness of any vaccine is uncertain when it depends on humoral response.[65107]

        Patients with altered immune states due to generalized neoplastic disease or an immune system compromised by radiation therapy or drug therapy (e.g., chemotherapy, organ transplant therapy, or corticosteroid therapy with greater than physiologic doses) may not have an adequate antibody response to the influenza virus vaccine. High dose corticosteroid therapy, defined as a dose equivalent of 2 mg/kg or more or 20 mg/day or more of prednisone administered for 14 days or more, may reduce the immune response to vaccine. Vaccination with influenza virus vaccine is recommended during chemotherapy and radiation therapy, although vaccination with other vaccines should be avoided due to potential suboptimal antibody response. Allogeneic stem cell transplant patients who received the influenza virus vaccine prior to hematopoietic stem cell transplant (HSCT) should receive repeat influenza virus vaccine doses routinely after HSCT. Administer the influenza virus vaccine at least 6 months after HSCT and annually thereafter. Patients may be vaccinated as early as 4 months after HSCT; however, a second dose should be considered.[65107] The influenza virus vaccine may be given as early as 1 month post solid organ transplant, but should be avoided during active treatment for rejection.[67938]

        Mechanism of Action

        Influenza virus vaccine imparts immunity against the influenza virus by stimulating production of antibodies that are specific to the disease. Vaccine recipients develop immunity only to those strains of the virus from which the vaccine was prepared. Influenza viruses are recognized by the surface antigens they carry, and two such antigens, hemagglutinin (H) and neuraminidase (N) have been identified and are used to classify the various viruses. Subtypes of these strains (H1, H2, H3, N1, N2) are associated with influenza A virus and have been recognized to cause disease in humans. Immunity to these surface antigens increases resistance to infection and decreases the severity of the disease if infection occurs. Eventually, antigenic variation can occur, and immunity to one strain may no longer impart immunity to distantly related subtypes of the virus. Influenza B viruses also exhibit antigenic variation, and new variants of both types of viruses continue to cause widespread epidemics of respiratory disease.[61129]

        Pharmacokinetics

        The inactivated influenza virus vaccine (IIV) is usually administered intramuscularly; intradermal vaccines are also available. The vaccine usually imparts a protective effect within 10 to 14 days of administration. Post-vaccine antibody titers are generally high enough in healthy young adults and children to provide resistance against infection by strains found in the vaccine as well as related strains. A hemagglutination-inhibiting antibody titer of at least 1:40 may be protective against influenza infection in up to 50% of people. Among 1,077 patients 18 to 64 years of age who got Afluria, 94.2 to 99.9% had a postvaccination titer of at least 1:40. The duration of immunity imparted by the influenza vaccine generally lasts 6 to 12 months.[61129]

        Special Populations

        Pediatrics

        Infants and Children 6 to 47 months

        Three clinical studies evaluated the immunogenicity of Fluvirin in healthy patients (n = 285) and those at increased risk for influenza complications (n = 41). Patients at increased risk were vaccinated with two 0.25 mL doses. After vaccination, 49% or more demonstrated at least a 4-fold increase in HI antibody titers to all strains, with titers of 1:40 or more in 71% or more of patients. A lower immune response was demonstrated for Fluvirin in 2 clinical studies when the vaccine was compared to 2 other spilt vaccines in patients 6 to 47 months of age, with the greatest differences demonstrated in those less than 36 months of age. Due to these differences, Fluvirin must only be used in patients 4 years of age or older.[41686]

         

        Infants and Children 6 months to 8 years

        The immunogenicity of Fluzone was evaluated in a multi-center study during which 68 infants and children 6 to 35 months of age were given 2 doses of 0.25 mL 26 days apart and 120 children 3 to 8 years were given 2 doses of 0.5 mL 30 days apart. Influenza vaccine was given during the previous flu season to 54.4% of those in the 6 to 35 months age group and 27.5% in the 3 to 8 years age group. One month after the last dose of the vaccine, HI antibody titers 1:40 or more in the younger age group occurred in 92.6% of patients (95% CI 83.7 to 97.6) for A (H1N1), 100% (94.7; 100) for A (H3N2), and 20.6% (11.7; 32.1) for the B strain. In the older age group, titers of 1:40 or more developed in 99.2% (95.4; 100) for A (H1N1), 100% (97; 100) for A (H3N2), and 58.3% (49; 67.3) for the B strain.[30823]

         

        Children and Adolescents 3 to 17 years

        A randomized, controlled, double-blind study assessed the immune response to the Fluarix quadrivalent vaccine (n = 791) compared to 2 different formulations of the trivalent Fluarix vaccine, TIV-1 (n = 818) and TIV-2 (n = 801). The quadrivalent vaccine demonstrated non-inferiority to the trivalent formulations at evaluation 28 days after the last vaccination. Seroconversion was defined as a pre-vaccination HI titer of less than 1:10 with a post-vaccination titer of 1:40 or more or at least a 4-fold increase in serum HI titer over baseline to 1:40 or more. Seroconversion occurred in the following percentages of patients for each strain: A/California/7/2009 (H1N1) 91.4% quadrivalent vs. 89.9 to 91.6% trivalent; A/Victoria/210/2009 (H2N2) 72.3% vs. 70.7 to 71.9%; B/Brisbane/60/2008 (Victoria lineage) 70% vs. 29.6 to 68.5%; B/Brisbane/3/2007 (Yamagata lineage) 72.5% vs. 37 to 70.8%. The additional B virus strain in the quadrivalent vaccine did not demonstrate immune interference with the other strains present in the vaccine.[52652]

        Geriatric

        The efficacy of Afluria in 206 healthy elderly patients (mean age of 72 years, range 65 to 93 years) was assessed by determining the percentage of patients with seroconversion, which was defined as a 4-fold increase in post-vaccination hemagglutination-inhibiting antibody titer if the pre-vaccination titer was at least 1:10 or an increase in titer to at least 1:40 if the pre-vaccination titer was less than 1:10. The mean seroconversion rate ranged from 34% to 45.6% for the 3 vaccine strains. After vaccination, 77.7 to 99.5% had a hemagglutination-inhibiting antibody titer of at least 1:40.[61129] The efficacy of the influenza virus vaccine among older patients was also examined in another study. Receipt of a single dose of the 2003/2004 influenza vaccine to patients either older or younger than 60 years on hemodialysis led to a significant increase from baseline in the percentage of patients with an antibody titer for each of the 3 vaccine strains of at least 1:40, which is considered protective against infection. Fewer older patients obtained a protective antibody titer. For example, 1 month after the dose, 94.7% of 19 patients 60 years of age or younger and 66.7% of 39 patients older than 60 years of age had protective antibody titers against the H1N1 component. The effect of a second dose given a month after the initial dose was examined. The percentage of patients with protective antibody titers did not significantly increase after a second dose. Further, geometric mean titers did not significantly increase after the second dose in either the younger or older patients. The strains in the 2003/2004 influenza vaccine were B/Hong Kong/330/2001(B), A/New Caledonia/20/99 (A/H1N1), and A/Panama/2007/99 (A/H3N2).[33455] In contrast to results obtained after a second dose, more adults at least 65 years of age seroconverted after receipt of Fluzone High-Dose (180 mcg influenza virus hemagglutinin) as compared with receipt of Fluzone (45 mcg influenza virus hemagglutinin). Among the Fluzone High-Dose recipients, 41.8% to 69.1% seroconverted as compared with 23.1% to 50.7% of Fluzone recipients. In another study, administering Fluzone High-Dose to patients 65 years of age and older (n = 15,892) was found to be statistically superior to Fluzone (n = 15,911) in reducing the number of laboratory confirmed influenza cases [1.43% (n = 227) vs. 1.89% (n = 300); 95% CI, 24.2 (9.7; 36.5)].[51849]

        Pregnancy/Breast-feeding

        pregnancy

        No adequate and well-controlled studies have been conducted in pregnant individuals. Based on available data from pregnancy registries of Flucelvax and Fluarix administered during pregnancy, there was no evidence of vaccine-associated risk of major birth defects or miscarriage. Data from a Pregnancy Exposure Registry in the U.S. looked at individuals vaccinated with Afluria quadrivalent vaccine during the influenza season 2017 to 2018 through 2020 to 2021. Of 483 pregnancies, 477 resulted in live births with 485 infants born. There were 2 stillbirths, neither with major birth defects (1 patient was vaccinated in the first trimester and 1 patient was vaccinated during the second trimester). There were 160 patients vaccinated before 20 weeks gestation, in these patients there were 4 spontaneous abortions (2.5%). Among the 171 patients vaccinated in the first trimester, there were 2 major birth defects (1.2%). In the 201 patients vaccinated in the second trimester, there were 2 major birth defects (1%). The data generated from this registry demonstrates rates of miscarriage and major birth defects that are consistent with the estimated background rates.[61129] During animal studies, no evidence of impaired fertility or fetal harm was noted with influenza vaccines. Pregnancy may increase the risk of serious medical complications from influenza. Therefore, the Advisory Committee on Immunization Practices (ACIP) recommends that all individuals who are or will be pregnant (in any trimester) during the influenza season be routinely vaccinated with an inactivated influenza vaccine (vs. live-attenuated influenza vaccine).[52652] [60831] [63436] The American College of Obstetricians and Gynecologist (ACOG) committee also recommends pregnant individuals receive the inactivated or recombinant influenza vaccine as soon as it becomes available. Ideally, the influenza vaccine should be given by the end of October in the United States, but vaccination during flu season can occur at anytime. It is safe and effective to administer other non-virus containing or inactive vaccines (Tdap, RSV, or Covid-19 vaccine) during the same visit.[70419] In addition to benefits to the mother, influenza vaccine administration during pregnancy appears to help protect newborns and infants. Fewer cases of laboratory-confirmed influenza occurred during the first 6 months of life among infants of the 159 mothers who received the inactivated influenza vaccine (6 cases) as compared with infants of 157 mothers who received the pneumococcal polysaccharide vaccine (16 cases). Some manufacturers have established pregnancy registries to monitor pregnancy outcomes and newborn health after vaccination. Patients who receive these vaccines during pregnancy are encouraged to enroll in these registries. For Sanofi Pasteur influenza vaccines (e.g., Fluzone and Flublok), patients are encouraged to contact Sanofi Pasteur at 800-822-2463.[52652] [54943] [55717] [60831] [61129] [61294] [64726] [65035]

        breast-feeding

        Data are limited regarding use of the influenza virus vaccine during breast-feeding, and its excretion in human breast milk is unknown. The Advisory Committee on Immunization Practices (ACIP) and the American Academy of Pediatrics (AAP) state inactivated virus vaccines pose no risk for mothers or their infants. Additionally, breast-feeding does not adversely affect immunization; limited data suggest breast-feeding may enhance the immune response to certain vaccine antigens. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally administered drug, health care providers are encouraged to report the adverse effect to the FDA.[52652] [54943] [55717] [60831] [61129] [61294] [63436] [64726] [65035] [65107]

[60092] [65107] Ocrelizumab: (Moderate) Administer all non-live vaccines at least 2 weeks before ocrelizumab initiation, whenever possible. Ocrelizumab may interfere with the effectiveness of non-live virus vaccines. Attenuated antibody responses to tetanus toxoid-containing vaccine, pneumococcal polysaccharide and pneumococcal conjugate vaccines, and seasonal influenza vaccine were observed in patients exposed to ocrelizumab at the time of vaccination during an open-label study. Infants born to mothers exposed to ocrelizumab during pregnancy may receive non-live vaccines as indicated before B-cell recovery; however, consider assessing the immune response to the vaccine. ACIP recommends that patients receiving any vaccination during immunosuppressive therapy or in the 2 weeks prior to starting therapy should be considered unimmunized and should be revaccinated a minimum of 3 months after discontinuation of therapy. Passive immunoprophylaxis with immune globulins may be indicated for immunocompromised persons instead of, or in addition to, vaccination. [43236] [61838] Ofatumumab: (Major) Administer all needed non-live vaccines according to immunization guidelines at least 2 weeks before initiation of ofatumumab.

When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine. [60092] [65107] Satralizumab: (Major) Administer all non-live vaccines according to immunization guidelines at least 2 weeks before initiation of satralizumab. [43236] [60092] [65841] Siponimod: (Moderate) Administer all non-live vaccines at least 2 weeks before siponimod initiation, whenever possible. Vaccines may be less effective if given during siponimod treatment. Patients should be considered unimmunized if vaccinated within a 14-day period before starting immunosuppresive therapy or during immunosuppressive therapy, and should they be revaccinated at least 3 months after therapy is discontinued if immune competence is restored. [64031] [65107] Triamcinolone: (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine. [60092] [65107] Ublituximab: (Moderate) Patients receiving immunosuppressant medications may have a diminished response to non-live vaccines. When feasible, administer indicated vaccines at least two weeks prior to initiating immunosuppressant medications. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving immunosuppressant medications about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine. [60092] [65107] [68398] Vamorolone: (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days.
