    Description/Classification

    Description

    The COVID-19 vaccine is an investigational vaccine that contains messenger RNA (mRNA) encoding the viral spike glycoprotein (S) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The COVID-19 vaccine is not an FDA-approved vaccine; however, the vaccine has been authorized for use under an Emergency Use Authorization (EUA) for active immunization for the prevention of coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 in patients 16 years of age and older (Pfizer-BioNTech COVID-19 vaccine) and 18 years of age and older (Moderna COVID-19 vaccine).[66080][66120] There are many clinical trials underway for various COVID-19 vaccines. Within the United States, phase 3 clinical trials currently include mRNA vaccines, viral vector-based vaccines, and protein-based vaccines.[66083] One of the advantages of mRNA vaccines is that they can be rapidly manufactured. The process is cell-free and can be scaled, allowing quick responses to large outbreaks and epidemics, such as the COVID-19 pandemic. Additionally, mRNA vaccines offer a different technology; unlike other vaccines, RNA-based vaccines introduce an mRNA sequence coded for a disease-specific antigen, which elicits a robust innate immune response when presented to the immune system.[66084][66093] In clinical trials, RNA-vaccines and RNA-based therapeutic agents have been found to be safe and well-tolerated. The most commonly reported adverse drug reactions include injection site pain, fever, chills, fatigue, muscle pain, and headache. Serious allergic reactions and anaphylaxis have been reported in patients outside of clinical trials during mass vaccination.[66084][66080][66120] In phase 1a of the vaccination program for COVID-19, the Advisory Committee on Immunization Practices (ACIP) recommends that both health care personnel and residents of long-term care facilities are the first to be offered the vaccine. Next, in phase 1b, frontline essential workers and persons aged 75 years and older will be offered vaccination. Phase 1c will consist of persons aged 65 to 74 years, persons aged 16 to 64 years with high-risk medical conditions, and essential workers not recommended for vaccination in Phase 1b. In the final phase (phase 2), all persons aged 16 years and older not previously recommended for vaccination are eligible.[66165]

     

    Emerging SARS-CoV-2 Virus Variants

    The mRNA COVID-19 vaccines are being tested against emerging coronavirus variants. Based on in vitro studies, Moderna reported no significant impact on neutralization of it's mRNA vaccine against the variant first isolated in the United Kingdom (B.1.1.7); however, a 6-fold geometric mean titer reduction against the variant first isolated in the Republic of South Africa (B.1.351) was seen. Pfizer has reported a small effect of its mRNA vaccine on neutralization titers against these variants compared to the parental virus strain based on in vitro studies; however, Pfizer's analysis did not include all the mutations found in the variants.[66352][66353][66354] Moderna is testing an additional booster dose of its mRNA COVID-19 vaccine as well as advancing an additional booster vaccine candidate against the emerging variant strain first identified in the Republic of South Africa into clinical studies. Pfizer is prepared to continue to conduct studies to monitor effectiveness against emerging variants and respond, if needed.[66355][66356]

     

    Pfizer-BioNTech Vaccine Trial Data

    Efficacy data for the Pfizer-BioNTech COVID-19 vaccine included 36,621 patients who did not have evidence of prior infection with SARS-CoV-2 through 7 days after the second dose. Of the study participants who received the Pfizer-BioNTech COVID-19 vaccine (n = 18,242), 51.1% were male and 48.9% were female, 82.8% were White, 8.9% were Black or African American, 4.5% were Asian, 0.6% were American Indian or Alaska Native, 0.3% were Native Hawaiian or other Pacific Islander, and 2.9% were either multiracial or not reported. Additionally, 72.7% were not Hispanic or Latino, 26.8% were Hispanic or Latino, and 0.6% were not reported. Patients who were immunocompromised and those who had a previous clinical or microbiological diagnosis of COVID-19 disease were excluded, along with pregnant and breast-feeding women. Patients with pre-existing stable disease, defined as diseases not requiring significant change in therapy or hospitalization for worsening disease during the 6 weeks before enrollment, were included as were participants with known stable infection with human immunodeficiency virus (HIV), hepatitis C virus (HCV), or hepatitis B virus (HBV). In an interim analysis, there were 8 confirmed COVID-19 cases in the Pfizer-BioNTech COVID-19 vaccine group and 162 cases in the placebo group. The overall efficacy of the Pfizer-BioNTech COVID-19 vaccine was 95% in patients without evidence of prior SARS-CoV-2 infection. In patients 16 to 64 years and 65 years and older, the efficacy was 95.1% and 94.7%, respectively. There were no significant clinical differences in overall vaccine efficacy in patients at risk of severe COVID-19 disease including those with 1 or more comorbidities that increase the risk of severe COVID-19 disease (e.g., asthma, BMI 30 kg/m2 or more, chronic pulmonary disease, diabetes mellitus, hypertension).[66080]

     

    Moderna Vaccine Trial Data

    Efficacy data for the Moderna COVID-19 vaccine included 28,207 patients who did not have evidence of prior infection with SARS-CoV-2 through 14 days after the second dose. Of the study participants, 52.6% were male and 47.4% were female, 79.5% were White, 9.7% were Black or African American, 4.6% were Asian, and 2.1% were other. Additionally, 19.7% were Hispanic or Latino. Patients who were immunocompromised were excluded, along with pregnant and breast-feeding women. Patients with pre-existing stable disease, defined as diseases not requiring significant change in therapy or hospitalization for worsening disease during the 3 months before enrollment, were included as were participants with known stable infection with human immunodeficiency virus (HIV). In the primary efficacy analysis, there were 11 confirmed COVID-19 cases in the Moderna COVID-19 vaccine group and 185 cases in the placebo group. The overall efficacy of the Moderna COVID-19 vaccine was 94.1% in patients without evidence of prior SARS-CoV-2 infection (95% CI, 89.3% to 96.8%; p less than 0.001). In patients 18 to 64 years and 65 years and older, the efficacy was 95.6% and 86.4%, respectively. Vaccine efficacy was also similar across other subgroups including presence of risk for severe COVID-19, sex, and race and ethnic group. A secondary endpoint of vaccine efficacy at preventing COVID-19 14 days after the first dose was 95.2%. The vaccine efficacy in the population that included patients who were SARS-CoV-2 seropositive at baseline was 93.6%. There were 30 cases of severe COVID-19 all occurring in patients who received placebo.[66120][66199]

    Administration Information

    General Administration Information

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

     

    Under the Emergency Use Authorization (EUA), healthcare providers are required to communicate to the patient, parent, or caregiver information consistent with the "Fact Sheet for Recipients and Caregivers" prior to the patient receiving the vaccine, including:

    • FDA has authorized the emergency use of this vaccine, which is not an FDA-approved vaccine.
    • The recipient or caregiver has the option to accept or refuse the COVID-19 vaccine.
    • The significant known and potential risks and benefits of the COVID-19 vaccine, and the extent to which such potential risks and benefits are unknown.
    • Available alternative vaccines in clinical trials or approved for use under other EUA and the risks and benefits of those alternatives.

    Under the EUA, vaccination providers enrolled in the federal COVID-19 Vaccination Program are required to report all vaccination administration errors, all serious adverse events, cases of Multisystem Inflammatory Syndrome (MIS) in adults and children, and cases of COVID-19 that result in hospitalization or death after administration of the vaccine.[66080]

     

    Storage and Handling Prior to Thawing (Pfizer-BioNTech COVID-19 vaccine)

    • Cartons of Pfizer-BioNTech COVID-19 vaccine vials arrive in thermal containers with dry ice. Once received, vials should be immediately transferred from the thermal container and preferably stored in an ultra-low temperature freezer between -80 to -60 degrees C (-112 to -76 degrees F) until the expiration date printed on the label.
    • Alternatively, Pfizer-BioNTech COVID-19 vaccine vials may be stored frozen at -25 to -15 degrees C (-13 to 5 degrees F) for up to 2 weeks. These vials may be returned 1 time to the recommended storage condition of -80 to -60 degrees C (-112 to -76 degrees F). Total cumulative time the vials are stored at -25 to -15 degrees C (-13 to 5 degrees F) should be tracked and should not exceed 2 weeks.
    • Protect from light until ready to use.
    • If an ultra-low temperature freezer is not available for storage of the Pfizer-BioNTech COVID-19 vaccine, the thermal container in which the vaccine arrives may be used as temporary storage when consistently refilled to the top with dry ice. The thermal container maintains a temperature range of -90 to -60 degrees C (-130 to -76 degrees F). Refer to the re-icing guidelines included in the original container for instructions regarding use for temporary storage.
    • Transportation of frozen vials: If local redistribution is needed and cartons containing vials cannot be transported at -90 to -60 degrees C (-130 to -76 degrees F), vials may be transported at -25 to -15 degrees C (-13 to 5 degrees F). Any hours used for transport at -25 to -15 degrees C (-13 to 5 degrees F) count against the 2-week limit for storage at -25 to -15 degrees C (-13 to 5 degrees F). Frozen vials transported at -25 to -15 degrees C (-13 to 5 degrees F) may be returned 1 time to the recommended storage condition of -80 to -60 degrees C (-112 to -76 degrees F).[66080]

     

    Storage and Handling Prior to Thawing (Moderna COVID-19 vaccine)

    • Store vaccine vials frozen between -50 to -15 degrees C (-58 to 5 degrees F) until ready to use. Keep in the original container to protect from light. Do not store on dry ice or below -50 degrees C (-58 degrees F).
    • Transportation of frozen vials: If transport at -50 to -15 degrees C (-58 to 5 degrees F) is not feasible, available data support transportation of 1 or more thawed vials for up to 12 hours at 2 to 8 degrees C (35 to 46 degrees F) when shipped using shipping containers which have been qualified to maintain 2 to 8 degrees C (35 to 46 degrees F) and under routine road and air transport conditions with shaking and vibration minimized. Once thawed and transported at 2 to 8 degrees C (35 to 46 degrees F), vials should not be refrozen and should be stored at 2 to 8 degrees C (35 to 46 degrees F) for up to 30 days until use.[66120]

    Route-Specific Administration

    Injectable Administration

    • Administer intramuscularly. Do not administer intravenously, intradermally, or subcutaneously.
    • Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit. Prior to dilution, the Pfizer-BioNTech COVID-19 vaccine is a white to off-white suspension and may contain white to off-white opaque amorphous particles. The diluted Pfizer-BioNTech COVID-19 vaccine is an off-white suspension and should not contain particulate matter.[66080] The Moderna COVID-19 vaccine is a white to off-white suspension. It may contain white or translucent product-related particles.[66120]
    • There is no available information on coadministration of the COVID-19 vaccine with other vaccines; do not mix with other vaccines or products in the same syringe.[66080][66120]
      • When possible, administer the COVID-19 vaccine alone, with a minimum interval of 14 days before or after administration of other vaccines. Other vaccines may be administered with the mRNA COVID-19 vaccine within a shorter period when the benefit of vaccination outweighs the potential unknown risks of vaccine coadministration (e.g., tetanus toxoid-containing vaccination as part of wound management, rabies vaccination for post-exposure prophylaxis, measles or hepatitis A vaccination during an outbreak) or to avoid barriers or delays to mRNA COVID-19 vaccination (e.g., in long-term care facility residents or healthcare personnel who received influenza or other vaccination). If mRNA COVID-19 vaccines are administered within 14 days of another vaccine, do not repeat the dose of either vaccine.
      • Do not delay the mRNA COVID-19 vaccine because of testing for tuberculosis (TB) infection. Testing for TB infection, using the tuberculin skin test (TST) or interfero-gamma release assay (IGRA) can be done before or during the same visit as vaccine administration. If TB testing can not be done at the same time, testing should be delayed by 4 weeks or more after the completion of mRNA COVID-19 vaccination. Patients who have active TB disease or an illness that is being evaluated as active TB disease can receive an mRNA COVID-19 vaccine.[66175]
    • A 30 minute observation period after vaccination is recommended for the following patient populations:
      • History of an immediate allergic reaction of any severity to a vaccine or injectable therapy
      • History of anaphylaxis due to any cause
    • A 15 minute observation period after vaccination is recommended for all other patients.[66175]

    Intramuscular Administration

    Pfizer-BioNTech COVID-19 vaccine

    Thawing

    • The Pfizer-BioNTech COVID-19 vaccine contains a volume of 0.45 mL, supplied as a frozen suspension that is preservative-free. Each vial must be thawed prior to dilution.
      • Thawing under refrigeration: Vials may be thawed and stored in the refrigerator [2 to 8 degrees C (35 to 46 degrees F)] for up to 5 days (120 hours). A carton of 25 or 195 vials may take up to 2 or 3 hours, respectively, to thaw in the refrigerator; fewer vials will require less time to thaw.
      • Transportation of vials thawed under refrigeration: Available data support transportation of 1 or more vials thawed under refrigeration at 2 to 8 degrees C (35 to 46 degrees F) for up to 12 hours. Any hours used for transport at 2 to 8 degrees C (35 to 46 degrees F) count against the 120-hour limit for storage at 2 to 8 degrees C (35 to 46 degrees F).
      • Thawing at room temperature: For immediate use, frozen vials may be thawed at room temperature [up to 25 degrees C (77 degrees F)] for 30 minutes. Undiluted vials may be stored at room temperature for no more than 2 hours.
      • Thawed vials may be handled in room light conditions; however, minimize exposure to room light and avoid exposure to direct sunlight and ultraviolet light during storage. Do NOT refreeze thawed vials.[66080]

     

    Dilution

    • Thawed vials must reach room temperature before dilution and must be diluted within 2 hours.
    • Before dilution, gently invert vial 10 times to mix. Do NOT shake.
    • Inspect liquid in the vial prior to dilution. The liquid should be a white to off-white suspension and may contain white to off-white amorphous particles.
    • Dilute the vaccine suspension in its original vial with 1.8 mL of 0.9% Sodium Chloride Injection. Do NOT use bacteriostatic 0.9% Sodium Chloride Injection or any other diluent. Equalize vial pressure before removing the needle from the vial by withdrawing 1.8 mL of air into the empty diluent syringe. Do not add more than 1.8 mL of diluent
    • After dilution, gently invert vial 10 times to mix. Do NOT shake.
    • Each vial contains up to 6 doses of 0.3 mL. Vial labels and cartons may state that after dilution, a vial contains 5 doses of 0.3 mL. The information on the EUA fact sheet supersedes the number of doses stated on vial labels and cartons.
    • Low dead-volume syringes and/or needles are preferred to extract up to 6 doses from a single vial. If using standard syringes and needles, the volume may not be sufficient to extract a sixth dose from a single vial. If the amount of vaccine remaining in the vial cannot provide a full dose of 0.3 mL, discard the vial and content; do not pool excess vaccine from multiple vials.
    • Record the date and time of dilution on the vial label.
    • Storage after dilution: Store between 2 and 25 degrees C (35 to 77 degrees F) and use within 6 hours from the time of dilution. Discard any vaccine remaining in vials after 6 hours. Diluted vials may be handled in room light conditions; however, minimize exposure to room light and avoid exposure to direct sunlight and ultraviolet light during storage. Do NOT freeze the diluted vaccine. If it is frozen, it must be discarded.[66080]

     

    Intramuscular Injection

    • After withdrawing the dose, administer immediately as an intramuscular injection.[66080]

     

    Moderna COVID-19 vaccine

    Thawing

    • The Moderna COVID-19 vaccine contains a frozen suspension that is preservative-free and must be thawed prior to use.
      • Maximum 11-dose vial (range: 10 to 11 doses):
        • Thawing in the refrigerator: Vials may be thawed and stored in the refrigerator [2 to 8 degrees C (36 to 46 degrees F)] for 2 hours 30 minutes. Allow vial to remain at room temperature for 15 minutes prior to administration.
        • Thawing at room temperature: Frozen vials may be thawed at room temperature [15 to 25 degrees C (59 to 77 degrees F)] for 1 hour.
      • Maximum 15-dose vial (range: 13 to 15 doses):
        • Thawing in the refrigerator: Vials may be thawed and stored in the refrigerator [2 to 8 degrees C (36 to 46 degrees F)] for 3 hours. Allow vial to remain at room temperature for 15 minutes prior to administration.
        • Thawing at room temperature: Frozen vials may be thawed at room temperature [15 to 25 degrees C (59 to 77 degrees F)] for 1 hour 30 minutes.
      • Do NOT refreeze thawed vials.
      • Thawed vials can be handled in room light conditions; however, minimize exposure to room light during storage.[66120]

     

    Preparation

    • Swirl vial gently after thawing and between each withdrawal. Do NOT shake. Do NOT dilute.
    • Withdraw each 0.5 mL dose using a new sterile needle and syringe to prevent transmission of infection between patients. Pierce the stopper at a different site each time.
    • The 11-dose vial contains a range of 10 to 11 doses and the 15-dose vial contains a range of 13 to 15 doses. Depending on the syringes and needles used for each dose, there may not be sufficient volume to extract more than 10 doses from the maximum of 11 doses vial or more than 13 doses from the maximum of 15 doses vial. If the amount of vaccine remaining in the vial cannot provide a full dose of 0.5 mL, discard the vial and content; do not pool excess vaccine from multiple vials.
    • Storage before vial has been needle-punctured:
      • Storage in refrigerator: Store between 2 and 8 degrees C (36 to 46 degrees F) for up to 30 days. Do NOT refreeze.
      • Storage outside refrigerated conditions: Vials may be stored between 8 and 25 degrees C (46 to 77 degrees F) for a total of 24 hours.
    • Storage after vial has been needle-punctured: Store between 2 and 25 degrees C (36 to 77 degrees F) and use within 12 hours from the time the needle punctures the vial to withdraw initial dose. Do NOT refreeze.[66120]

     

    Intramuscular Injection

    • After withdrawing the dose, administer immediately as an intramuscular injection.[66120]

In general, the rates and severity of the reactions were slightly higher after the second dose compared to after the first.[66080] [66120] After Pfizer-BioNTech COVID-19 vaccine administration, pain (84.1%), erythema or redness (9.5%), and swelling (10.5%) at the injection site were the most common reactions in patients 16 years and older. Most local reactions resolved within 3 days, but some patients reported symptoms for up to 36 days. About one-third (28.3% to 32%) of patients 18 to 55 years who received the vaccine reported pain that either interfered with daily activity or prevented it; the percentage of patients reporting this degree of pain (15.2% to 18.5%) was lower in patients 56 years and older. The largest difference occurred in the incidence of redness in patients 56 years and older (7.2% after dose 2, 4.7% after dose 1).[66080] After Moderna COVID-19 vaccine administration, pain at the injection site was reported in 92% of patients. The highest rates of pain were in patients 18 to 64 years after dose 2, with 89.9% reporting pain and 4.6% reporting that it prevented daily activity and required the use of pain relievers. Erythema or redness (8.9% after dose 2, 3% after dose 1) and swelling or hardness (12.6% after dose 2, 6.7% after dose 1) were reported in patients 18 to 64 years. Similar numbers of erythema or redness (7.5% after dose 2, 2.3% after dose 1) and swelling or hardness (10.8% after dose 2, 4.4% after dose 1) were reported in patients 65 years and older. Axillary swelling or tenderness was more common after the second dose in both age groups (18 to 64 years: 16.2% after dose 2, 11.6% after dose 1 and 65 years and older: 8.5% after dose 2, 6.1% after dose 1). Most local reactions lasted 1 to 3 days. Delayed reactions, occurring 8 or more days after administration, occurred in 0.8% and 0.2% of patients after the first and second dose, respectively, and usually resolved over 4 to 5 days.[66120] [66199] Patients who have received dermal fillers may develop swelling at or near the site of filler injection (usually face or lips) after mRNA COVID-19 vaccine administration. It appears to be temporary and can resolve with medical treatment, including corticosteroid therapy. These patients may receive mRNA COVID-19 vaccines without additional precautions; however, they should be advised to contact their health care provider if they develop swelling at or near the site of dermal filler after vaccination.[66175]

      During clinical trials, fatigue (62.9% to 70%), headache (55.1% to 64.7%), and malaise (0.5%) occurred after administration of the COVID-19 vaccine. The rates and severity of the reactions were generally higher after the second dose compared to the first dose.[66080] [66120] In patients 18 to 55 years of age who received the Pfizer-BioNTech COVID-19 vaccine, moderate fatigue (causing some interference with activity) was reported in majority of patients experiencing fatigue (33.7% after dose 2, 19.9% after dose 1). In patients 56 years and older, moderate fatigue was also reported by more patients after the second dose (26.6% after dose 2, 13.3% after dose 1). Headache was more common after the second dose in both age groups (18 to 55 years: 51.7% after dose 2, 41.9% after dose 1 and 56 years and older: 39% after dose 2, 25.2% after dose 1).[66080] In Moderna COVID-19 vaccine clinical trials, fatigue (70%) was the most frequently reported systemic adverse reaction. The highest incidence of fatigue was reported by patients 18 to 64 years after the second dose, with 67.6% reporting any fatigue, 10.7% reporting fatigue that prevented daily activities, and 1 patient reporting fatigue that required an emergency room visit or hospitalization. Headache was more common after the second dose in both age groups (18 to 64 years: 62.8% after dose 2, 35.3% after dose 1 and 65 years and older: 46.2% after dose 2, 24.5% after dose 1).[66120]

      Musculoskeletal adverse reactions reported during COVID-19 vaccine clinical trials include muscle pain or myalgia (38.3% to 61.5%) and/or joint pain or arthralgia (23.6% to 46.4%).[66080] [66120] In patients 18 to 55 years of age, new or worsened muscle pain was reported in about one-third of patients (37.3%) after the second Pfizer-BioNTech COVID-19 vaccine dose compared to 21.3% after the first dose. A similar number of patients 56 years or older reported new or worsened muscle pain (28.7% after dose 2, 13.9% after dose 1). Moderate to severe muscle pain (causing some interference with daily activities or preventing activities) was reported after dose 2 in 21.7% of patients 18 to 55 years and 16.6% of patients 56 years and older. New or worsened joint pain was reported in approximately twice as many patients after the second dose compared to the first dose in both age groups (18 to 55 years: 21.9% after dose 2, 11% after dose 1 and 56 years and older: 18.9% after dose 2, 8.6% after dose 1).[66080] During Moderna COVID-19 clinical trials, myalgia was more common after the second dose in both age groups (18 to 64 years: 61.6% after dose 2, 23.7% after dose 1 and 65 years and older: 47.1% after dose 2, 19.7% after dose 1). Myalgia that prevented daily activity was reported in significantly more patients after the second dose (18 to 64 years: 10.1% after dose 2, 0.6% after dose 1 and 65 years and older: 5.6% after dose 2, 0.5% after dose 1). Similar to myalgia, arthralgia was more common after the second dose in both age groups (18 to 64 years: 45.5% after dose 2, 16.6% after dose 1 and 65 years and older: 35% after dose 2, 16.4% after dose 1). Arthralgia that prevented daily activity was reported in significantly more patients after the second dose (18 to 64 years: 5.9% after dose 2, 0.4% after dose 1 and 65 years and older: 3.3% after dose 2, 0.3% after dose 1). One case of arthralgia requiring an emergency room visit or hospitalization was reported in the vaccine group.[66120]

      Diarrhea, nausea, and vomiting were reported during COVID-19 vaccine clinical trials.[66080] [66120] During clinical trials in patients 16 years and older, nausea (1.1%) was reported after administration of the Pfizer-BioNTech COVID-19 vaccine. Diarrhea was reported by 10.4% to 11.1% of patients 18 to 55 years and 8.3% of patients 56 years and older. Vomiting was reported in 1.2% to 1.9% of patients 18 to 55 years and 0.5% to 0.7% of patients 56 years and older.[66080] During Moderna COVID-19 vaccine clinical trials, nausea and/or vomiting was reported in twice as many patients 18 to 64 years after dose 2 (21.4%) compared to dose 1 (9.4%). A similar difference was seen in patients 65 years and older (11.8% after dose 2; 5.2% after dose 1). One case of intractable nausea and vomiting requiring hospitalization was reported as a serious adverse reaction in the vaccine group.[66120]

      Lymphadenopathy was reported in 0.3% of patients 16 years and older during Pfizer-BioNTech COVID-19 vaccine clinical trials. From dose 1 through 20 days after dose 2, lymphadenopathy was reported in more patients in the vaccine group (n = 64) than in the placebo group (n = 6).[66080] During Moderna COVID-19 vaccine clinical trials, lymphadenopathy-related events were reported in 1.1% of patients who received the vaccine compared to 0.6% of patients who received placebo. These events included lymphadenopathy, lymphadenitis, lymph node pain, vaccination-site lymphadenopathy, injection-site lymphadenopathy, and axillary mass.[66120]

      Serious allergic reactions or anaphylactoid reactions have been reported in patients outside of clinical trials during mass vaccination. During phase 2/3 Pfizer-BioNTech COVID-19 vaccine clinical trials, a subset of patients in the vaccinated group had hypersensitivity-related adverse reactions, possibly representing allergic reactions (0.63% vs. 0.51%, placebo).[66080] [66175] During mass vaccination with the Pfizer-BioNTech COVID-19 vaccine outside of clinical trials, severe allergic reactions, including anaphylaxis and other hypersensitivity reactions (e.g. rash, pruritus, urticaria, angioedema), have been reported.[66080] During this time, 21 cases of anaphylaxis were identified (a rate of 11.1 anaphylaxis cases per million doses administered). Of those, 17 patients had a documented history of allergies or allergic reaction and 7 patients had a history of anaphylaxis. Median time to symptom onset was 13 minutes (range = 2 to 150 minutes). Twenty patients were available for follow-up and all had recovered or been discharged home. An additional 83 nonanaphylaxis allergic reactions were reported; symptoms included pruritus, rash, itchy and scratchy sensation in the throat, and mild respiratory symptoms. Median time to symptom onset was 12 minutes (range = less than 1 minute to 20 hours). In most patients (85%), symptoms occurred within 30 minutes. For 67% of patients, a past history of allergies or allergic reactions was documented.[66397] During Moderna COVID-19 clinical trials, hypersensitivity related adverse reactions were reported in 1.5% of vaccine recipients compared to 1.1% of placebo recipients. Hypersensitivity reactions included injection site rash and injection site urticaria.[66120] During mass vaccination with the Moderna vaccine, 10 cases of anaphylaxis were identified (a rate of 2.5 anaphylaxis cases per million doses administered). Of those, 9 patients had a documented history of allergies or allergic reaction and 5 patients had a history of anaphylaxis. Median time to symptom onset was 7.5 minutes (range = 1 to 45 minutes). Eight patients were available for follow-up and all had recovered or been discharged home. An additional 43 nonanaphylaxis allergic reactions were reported; symptoms included pruritus, rash, itchy and scratchy sensation in the throat, sensations of throat closure, and mild respiratory symptoms. Median time to symptom onset was 15 minutes (range = less than 1 minute to 24 hours). In most patients (73%), symptoms occurred within 30 minutes. For 60% of patients, a past history of allergies or allergic reactions was documented.[66398]

      During Pfizer-BioNTech COVID-19 vaccine clinical trials, appendicitis was reported as a serious adverse reaction in 8 patients receiving vaccine (n = 18,801) vs. 4 receiving placebo (n = 18,785). Bell's palsy (facial paralysis) was reported by 4 patients in the Pfizer-BioNTech COVID-19 vaccine group (n = 18,801) compared to none of the patients in the placebo group. Onset of facial paralysis occurred on day 37 after dose 1 (patient did not receive dose 2) and days 3, 9, and 48 after dose 2. During Moderna COVID-19 vaccine clinical trials, there were 3 reports of Bell's palsy in the vaccine group (n = 15,185) compared to 1 patient in the placebo group (n = 15,166). Onset of facial paralysis occurred 22, 28, and 32 days after vaccination in the vaccine group and 17 days after vaccination in the placebo group. In the United States, it is estimated that between 25 and 35 in 100,000 people are affected with Bell's palsy. Currently available information is insufficient to determine a causal relationship between appendicitis or Bell's palsy with the vaccine.[66080] [66120] [66184]

      During clinical trials, chills (31.9% to 45.4%) and fever (14.2% to 15.5%) occurred after administration of the COVID-19 vaccine. The rates and severity of the reactions were generally higher after the second dose compared to the first dose.[66080] [66120] In patients 18 to 55 years, fever of 101.2 degrees F (38.4 degrees C) or higher was reported in 6 times more patients after the second Pfizer-BioNTech COVID-19 vaccine dose (6.4% after dose 2, 1% after dose 1). In patients 56 years and older, fever of 101.2 degrees F (38.4 degrees C) or higher was reported in 3% of patients after dose 2 compared to 0.3% of patients after dose 1. In patients 18 to 55 years old, chills were reported by more patients after the second Pfizer-BioNTech COVID-19 vaccine dose (35.1% after dose 2, 14% after dose 1). A similar difference in the incidence of chills was seen in patients 56 years and older (22.7% after dose 2, 6.3% after dose 1).[66080] After Moderna COVID-19 vaccine administration, fever was reported in more patients 18 to 64 years after dose 2 (17.4%) compared to dose 1 (0.9%). A fever of 102.1 degrees F (38.9 degrees C) or higher was reported by 1.7% of patients after dose 2 compared to less than 0.1% after dose 1. Significantly more patients 65 years and older also reported fever after the second dose (10% after dose 1, 0.3% after dose 2). A fever of 102.1 degrees F (38.9 degrees C) or higher was reported by 0.5% of patients after dose 2 compared to less than 0.1% after dose 1. The greatest incidence of chills occurred after dose 2 in patients 18 to 64 years (48.6%).[66120]

      The COVID-19 vaccine is contraindicated in patients with a history of a severe allergic reaction to any component of the vaccine. The CDC considers an immediate allergic reaction (occurring within 4 hours of administration) of any severity to a previous dose of COVID-19 vaccine or any of its components or a severe allergic reaction (i.e., anaphylaxis) after a previous dose or to a component of the COVID-19 vaccine a contraindication to COVID-19 vaccination. A known polyethylene glycol (PEG) allergy is a contraindication to the mRNA COVID-19 vaccines. PEG is an ingredient in both mRNA COVID-19 vaccines and polysorbate 80 is an ingredient in the Janssen COVID-19 vaccine; cross-reactive hypersensitivity between these compounds may occur. Patients with a contraindication to 1 type of COVID-19 vaccine (i.e, mRNA) have a precaution to the other (i.e., adenovirus). However, because of potential cross-reactive hypersensitivity between the ingredients in both vaccines, consider evaluation by an allergist-immunologist in patients with a known allergy to these ingredients before they receive COVID-19 vaccination. Administration of antihistamines is not recommended for allergic reaction prophylaxis prior to vaccination as they can mask cutaneous symptoms and delay the diagnosis and management of anaphylaxis. Delayed-onset local reactions (e.g., erythema, induration, pruritus), which are sometimes quite large, have been reported beginning a few days through the second week after the first mRNA COVID-19 vaccine dose in some patients. Patients with only a delayed-onset local reaction around the injection site area after the first vaccine dose are not thought to be at risk for anaphylaxis when receiving the second dose and do not have a contraindication or precaution to the second dose. These patients should still receive the second dose using the same vaccine product as the first dose and at the recommended interval, preferably in the opposite arm. As with any biologic product, the prescriber or healthcare professional should have procedures in place to manage allergic reactions. If an anaphylactic or other clinically significant hypersensitivity reaction occurs, institute appropriate therapy and immediately discontinue administration of the vaccine. The healthcare 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 vaccine.[66080][66120][66175] When vaccinating patients with allergies, a 30 minute observation period is recommended for patients with a history of an immediate allergic reaction of any severity to a vaccine or injectable therapy, patients with a history of anaphylaxis due to any cause, or patients with a contraindication to a different COVID-19 vaccine than the 1 they are receiving. A 15 minute observation period is recommended for all other patients.[66175]

      Immunocompromised patients, including patients with immunosuppression or receiving immunosuppressive therapy, may not have an adequate immune response to the COVID-19 vaccine.[66080] [66120] Counsel patients about the unknown vaccine safety profile and effectiveness in immunocompromised patients, the potential for reduced immune responses, and the need to continue following precautions to avoid exposure to the SARS-CoV-2 virus.[66175] Immunosuppressed persons may include patients with severe combined immunodeficiency (SCID), hypogammaglobulinemia, agammaglobulinemia, or an immune system compromised by drug therapy (i.e., corticosteroid therapy with greater than physiologic doses). Short-term (less than 2 weeks) corticosteroid therapy or intra-articular, bursal, or tendon injections with corticosteroids should not be immunosuppressive.[65107] Ideally, COVID-19 vaccination should be completed at least 2 weeks before initiation of immunosuppressive therapies. When it is not possible to administer the COVID-19 vaccine in advance, people on immunosuppressive therapy can still receive COVID-19 vaccination. Antibody testing is not recommended to assess for immunity after COVID-19 vaccination. Re-vaccination is not recommended after immune competence is regained in patients who received mRNA COVID-19 vaccines during treatment with immunosuppressive drugs. For patients receiving antibody therapies not specific to COVID-19 treatment (e.g., intravenous immunoglobulin, RhoGAM), there is no recommended minimum interval between these therapies and administration of mRNA COVID-19 vaccines. Administration of mRNA COVID-19 vaccines either together or at any interval before or after receipt of an antibody-containing product is unlikely to substantially impair the development of a protective antibody response.[66175]

      Patients with altered immune states due to generalized neoplastic disease or an immune system compromised by radiation therapy or chemotherapy may not have an adequate immune response to the COVID-19 vaccine.[65107] [66080] [66120] Counsel patients about the unknown vaccine safety profile and effectiveness in immunocompromised patients, the potential for reduced immune responses, and the need to continue following precautions to avoid exposure to the SARS-CoV-2 virus. Antibody testing is not recommended to assess for immunity after COVID-19 vaccination. Re-vaccination is not recommended after immune competence is regained in patients who received mRNA COVID-19 vaccines during chemotherapy or treatment with other immunosuppressive drugs.[66175] Vaccination should be delayed for at least 3 months after hematopoietic cell transplantation (HCT) or engineered cellular therapy (e.g. CAR-T cells) to maximize vaccine efficacy. For patients with hematologic malignancies receiving intensive cytotoxic chemotherapy (e.g., cytarabine/anthracycline-based induction regimens for AML), delay vaccination until absolute neutrophile count (ANC) recovery. For patients with solid tumor malignancies undergoing major surgery, separate date of surgery from vaccination by at least a few days to allow symptoms (e.g. fever) to be correctly attributed to surgery vs. vaccination. For more complex surgeries (e.g. splenectomy or surgery that may lead to an immunosuppressive state) surgeons may recommend a wider window (+/- 2 weeks) from the time of surgery.[66335]

      Postponing vaccination with the COVID-19 vaccine is recommended in patients with an acute moderate to severe illness or infection, both before the first vaccine or before the second vaccine if infection develops after the first vaccine administration. Patients who have active tuberculosis (TB) disease or an illness that is being evaluated as active TB disease can receive an mRNA COVID-19 vaccine. If vaccination is not deferred, observe the patient for 15 minutes after vaccine administration.[66175]

      Clinical trials for the vaccine were expanded to include patients with chronic, stable human immunodeficiency virus (HIV) infection. Efficacy information for the COVID-19 vaccine is not yet available in this patient population and although patients with HIV infection or acquired immunodeficiency syndrome (AIDS) could have a diminished response, the COVID-19 vaccine should be offered to patients with chronic, stable HIV.[65107] [66080] [66086] [66120] Counsel patients about the unknown vaccine safety profile and effectiveness in immunocompromised patients, the potential for reduced immune responses, and the need to continue following precautions to avoid exposure to the SARS-CoV-2 virus. When vaccinating immunocompromised patients, observe patients for 15 minutes after vaccine administration.[66175]

      The COVID-19 vaccine is administered by intramuscular (IM) injection only. Carefully consider the risks and benefits in patients at increased risk for bleeding after an intramuscular injection, such as thrombocytopenia, bleeding disorders (e.g., hemophilia), coagulopathy, vitamin K deficiency, and those receiving anticoagulant therapy. Caution and appropriate precautions to minimize the risk of bleeding or hematoma formation are advised.[65107] [66080] [66120]

      Available data are insufficient to inform vaccine-associated risks during pregnancy. It is unknown whether administration of the COVID-19 vaccine can cause fetal harm or affect the reproductive system.[66080] [66120] The American College of Obstetricians and Gynecologists (ACOG) recommends that women eligible for the COVID-19 vaccine be offered the vaccine regardless of pregnancy status. Women planning to become pregnant who are eligible for the COVID-19 vaccine are encouraged to complete their vaccination series prior to conception to ensure maximal protection prior to pregnancy. If a woman becomes pregnant after the first dose, administer the second dose as indicated. If a woman becomes pregnant within 30 days of receipt of the vaccine, encourage participation in the CDC's V-SAFE program.[66179] There are no recommendations for routine pregnancy testing before COVID-19 vaccination. Patients who are trying to become pregnant do not need to avoid pregnancy after COVID-19 vaccination. There is no evidence that any of the COVID-19 vaccines affect future fertility.[66175] In a prospective cohort study of 131 mRNA COVID-19 vaccine recipients (84 pregnant, 31 lactating, and 16 non-pregnant), vaccine-induced antibody titers were equivalent in pregnant and lactating women compared to non-pregnant women. All titers were significantly higher than those induced during SARS-CoV-2 infection during pregnancy. Vaccine-generated antibodies were present in all umbilical cord blood samples; neutralizing antibody titers were lower in umbilical cord compared to maternal sera, although statistical significance was not reached. No differences in reactogenicity were noted between the groups.[66558] A pregnancy exposure registry is available that monitors pregnancy outcomes in women exposed to Moderna COVID-19 vaccine during pregnancy. Encourage women vaccinated with Moderna COVID-19 vaccine to enroll in the registry by calling 1-866-663-3762.[66120] In developmental toxicity studies, when the same quantity of mRNA and other ingredients included in a single human dose of Moderna (100 mcg mRNA) and Pfizer-BioNTech (30 mcg mRNA) COVID-19 vaccines were administered to female rats by the IM route on 4 occasions, no vaccine-related adverse effects on female fertility, fetal development, or postnatal development were reported.[66080] [66120]

      There are no data regarding use of the COVID-19 vaccine during breast-feeding and its excretion in human breast milk is unknown.[66080] [66120] The American College of Obstetricians and Gynecologists (ACOG) recommends that breast-feeding women eligible for the COVID-19 vaccine be offered the vaccine.[66179] In a prospective cohort study of 131 mRNA COVID-19 vaccine recipients (84 pregnant, 31 lactating, and 16 non-pregnant), vaccine-induced antibody titers were equivalent in pregnant and lactating women compared to non-pregnant women. All titers were significantly higher than those induced during SARS-CoV-2 infection during pregnancy. Vaccine-generated antibodies were present in all breastmilk samples. No differences in reactogenicity were noted between the groups.[66558] If a breast-feeding infant experiences an adverse event possibly related to a maternally administered vaccine, health care providers are encouraged to report the adverse event to the FDA.[66080]

      Mechanism of Action

      The Pfizer-BioNTech COVID-19 vaccine contains nucleoside-modified messenger RNA (modRNA) and the Moderna COVID-19 vaccine is made up of a synthetic messenger RNA (mRNA), both encoding the viral spike glycoprotein (S) of SARS-CoV-2. The RNA is encapsulated in lipid nanoparticles, which enables entry into host cells, expression of the S protein, and elicitation of both antibody and cellular immune responses.[66080][66120]

      Pharmacokinetics

      The COVID-19 vaccine is administered intramuscularly. Vaccination does not ensure immunity.[66080][66120]

       

      Affected cytochrome P450 isoenzymes: none

      Route-Specific Pharmacokinetics

      Intramuscular Route

      After Pfizer-BioNTech COVID-19 vaccine administration, the highest neutralization titers were measured on day 28 (i.e., 7 days after the second dose) or on day 35 (i.e., 14 days after the second dose). The 50% neutralizing geometric mean titers (GMTs) on day 28 or 35 ranged from 1.7 to 3.8 times the GMT of the convalescent serum panel in patients 18 to 55 years of age and from 1.6 to 2.2 times the GMT of the convalescent serum panel in patients 65 to 85 years of age.[66103][66104]

       

      After 2 Moderna COVID-19 vaccinations, seroconversion occurred in all patients by day 15. All geometric mean titers (GMTs) exceeded those seen in convalescent serum by day 57. At day 43, neutralizing activity against SARS-CoV-2 was seen in all evaluated patients.[66185]

      Special Populations

      Geriatric

      The Pfizer-BioNTech COVID-19 vaccine generally elicited lower antigen-binding IgG and virus-neutralizing responses in patients 65 to 85 years of age compared to patients 18 to 55 years of age. However, on day 28 (i.e., 7 days after the second dose) and on day 35 (i.e., 14 days after the second dose), the 50% and 90% neutralizing geometric mean titers (GMTs) elicited in older adults exceeded those of the convalescent serum panel.[66103][66104]

      Pregnancy/Breast-feeding

      pregnancy

      Available data are insufficient to inform vaccine-associated risks during pregnancy. It is unknown whether administration of the COVID-19 vaccine can cause fetal harm or affect the reproductive system.[66080] [66120] The American College of Obstetricians and Gynecologists (ACOG) recommends that women eligible for the COVID-19 vaccine be offered the vaccine regardless of pregnancy status. Women planning to become pregnant who are eligible for the COVID-19 vaccine are encouraged to complete their vaccination series prior to conception to ensure maximal protection prior to pregnancy. If a woman becomes pregnant after the first dose, administer the second dose as indicated. If a woman becomes pregnant within 30 days of receipt of the vaccine, encourage participation in the CDC's V-SAFE program.[66179] There are no recommendations for routine pregnancy testing before COVID-19 vaccination. Patients who are trying to become pregnant do not need to avoid pregnancy after COVID-19 vaccination. There is no evidence that any of the COVID-19 vaccines affect future fertility.[66175] In a prospective cohort study of 131 mRNA COVID-19 vaccine recipients (84 pregnant, 31 lactating, and 16 non-pregnant), vaccine-induced antibody titers were equivalent in pregnant and lactating women compared to non-pregnant women. All titers were significantly higher than those induced during SARS-CoV-2 infection during pregnancy. Vaccine-generated antibodies were present in all umbilical cord blood samples; neutralizing antibody titers were lower in umbilical cord compared to maternal sera, although statistical significance was not reached. No differences in reactogenicity were noted between the groups.[66558] A pregnancy exposure registry is available that monitors pregnancy outcomes in women exposed to Moderna COVID-19 vaccine during pregnancy. Encourage women vaccinated with Moderna COVID-19 vaccine to enroll in the registry by calling 1-866-663-3762.[66120] In developmental toxicity studies, when the same quantity of mRNA and other ingredients included in a single human dose of Moderna (100 mcg mRNA) and Pfizer-BioNTech (30 mcg mRNA) COVID-19 vaccines were administered to female rats by the IM route on 4 occasions, no vaccine-related adverse effects on female fertility, fetal development, or postnatal development were reported.[66080] [66120]

      breast-feeding

      There are no data regarding use of the COVID-19 vaccine during breast-feeding and its excretion in human breast milk is unknown.[66080] [66120] The American College of Obstetricians and Gynecologists (ACOG) recommends that breast-feeding women eligible for the COVID-19 vaccine be offered the vaccine.[66179] In a prospective cohort study of 131 mRNA COVID-19 vaccine recipients (84 pregnant, 31 lactating, and 16 non-pregnant), vaccine-induced antibody titers were equivalent in pregnant and lactating women compared to non-pregnant women. All titers were significantly higher than those induced during SARS-CoV-2 infection during pregnancy. Vaccine-generated antibodies were present in all breastmilk samples. No differences in reactogenicity were noted between the groups.[66558] If a breast-feeding infant experiences an adverse event possibly related to a maternally administered vaccine, health care providers are encouraged to report the adverse event to the FDA.[66080]
