Medication Administration: Vaccines for Immunizations (Ambulatory) - CE


Follow instructions for SARS-COV2 vaccine administration provided on Elsevier’s Vaccination Hub https://elsevier.health/en-US/preview/sars-cov2-vaccine or Clinical Key for Nursing https://www.clinicalkey.com/nursing/#!/content/drug_monograph/6-s2.0-5295.

Take steps to eliminate interruptions and distractions during medication preparation.

Take extra care with a patient who takes medications that increase the risk for bleeding.9


Vaccination typically begins shortly after birth and continues into adulthood. During infancy and childhood, vaccine administration is more frequent, and multiple vaccines are typically administered, according to the recommended immunization schedule.4 If vaccines are missed, there are alternative schedules available to make up for the needed vaccines;3 however, this also means that the child may receive more vaccinations in one visit. During adolescence and into adulthood, the frequency of immunizations decreases; however, the human papillomavirus (HPV) vaccine is typically added for this age group. During young and middle adulthood, the frequency of scheduled vaccinations decreases. Additional booster vaccines may be given depending on the age at that initial immunization.2 By late adulthood, the addition of the pneumococcal vaccine (PCV) is recommended for those 65 and over. During pregnancy and while breastfeeding, there are certain vaccines that could pose a risk to the fetus and therefore are not recommended.1 As with any medication, vaccine administration should be at the practitioner’s discretion.

Vaccines can be given in combination when more than one inoculant is in one prefilled syringe (e.g., measles, mumps, and rubella [MMR] vaccine). This allows more immunizations with fewer injections. Combination vaccines are those that are licensed and sold already combined in a single syringe or those combined at the point of care as recommended by the manufacturer.

Simultaneous inoculation is defined as multiple vaccines given during the same visit. Giving simultaneous vaccines can allow for fewer visits but should be balanced with the discomfort of receiving several vaccines in one day. If the family seems unlikely to return for additional vaccines or is unwilling to comply with a catch-up schedule, simultaneous vaccines should be provided.6 Consideration should be given to the patient’s age and size and to vaccines with a greater risk of causing a local reaction (e.g., PCV, diphtheria, tetanus, and pertussis [DTaP]). Two live vaccines should not be given in the same muscle mass.5,6

The manufacturer’s instructions for use should be followed for storage and administration of vaccines. Prefilled syringes are considered activated once the cap is removed or a needle is attached. Activated vaccines should be used by the end of the facility’s day and then discarded. Activation should be avoided until the vaccine is needed.

There are very few strict contraindications for vaccines. Generally, a previous severe anaphylactic reaction or encephalopathy not attributable to another cause are contraindications. Precautions surrounding specific vaccines should be reviewed (e.g., live attenuated vaccines should not be given to immunosuppressed patients).

There are several routes by which vaccines may be given. These include oral, intramuscular (IM), intradermal, subcutaneous (Figure 1)Figure 1, and intranasal. The manufacturer’s instructions should be followed for recommended routes. For IM injections, the anterolateral aspect of the thigh (vastus lateralis muscle) (Figure 2)Figure 2 is recommended for infants (up to 12 months old) as the largest muscle mass. For children more than 12 months old and adults, the upper outer aspect of the deltoid (Figure 3)Figure 3 is recommended.6 For subcutaneous injections, the skin over the lateral thigh or upper outer aspect of the upper arm is recommended. The Centers for Disease Control and Prevention’s (CDC’s) guidelines should be followed for needle sizes and lengths according to age and muscle size.7

Adverse reactions rarely occur after vaccinations but may include anaphylaxis, anaphylactic shock, and neurologic deficits.6 Vaccine adverse event reporting is monitored by the CDC.

If the patient expresses concern regarding the accuracy of a medication, the medication should not be given. The patient’s concern should be explored, the practitioner notified, and the order verified.

  • Explain the importance of vaccination and keeping to the schedule as much as possible.
  • Explain the risks related to the procedure, including hematoma formation, nerve injury, and allergic reaction to the vaccine.
  • Instruct the patient regarding the potential side effects of the medication.
  • Instruct the patient to observe injection sites for complications and instruct him or her on when to seek additional care.
  • Prepare the patient for the possibility of signs and symptoms of illness associated with the vaccine. Explain that this is a normal reaction and not an actual illness.
  • Instruct the patient to take an up-to-date list of medications (over-the-counter [OTC], supplements, and prescriptions), including those prescribed from all practitioners, every time he or she visits a practitioner.9
  • Encourage questions and answer them as they arise.


  1. Perform hand hygiene.
  2. Introduce yourself to the patient.
  3. Verify the correct patient using two identifiers.
  4. Explain the procedure to the patient and ensure that he or she agrees to treatment.
  5. Ensure that evaluation findings are communicated to the clinical team leader per the organization’s practice.
  6. Evaluate the patient for specific contraindications or precautions related to vaccine administration (e.g., previous anaphylaxis with vaccine).
  7. Evaluate the patient’s knowledge regarding the vaccine(s) to be received.
  8. Evaluate the patient’s history of allergies, including medication or food allergies, and previous allergic reactions.
  9. Review the patient’s previous verbal and nonverbal responses to injections.
  10. Obtain the patient’s vital signs and his or her medical and medication history.
  11. Obtain the patient’s actual weight in kilograms.8 Stated, estimated, or historical weight should not be used.8
  12. Check accuracy and completeness of the practitioner’s original order.
  13. Obtain the medication and verify the expiration date.
  14. Inspect the medication for particulates, discoloration, or other loss of integrity.
    Do not use any medication that is cloudy or precipitated unless such is indicated by its manufacturer as being safe; otherwise, this may lead to harmful reactions.
  15. Understand drug reference information pertinent to the medication’s action, purpose, onset of action and peak action, normal dose, and common side effects.
  16. Ensure the six rights of medication safety: right medication, right dose, right time, right route, right patient, and right documentation.
  17. Label all medications , medication containers, and other solutions. The only exceptions are medications that are still in their original container or medications that are administered immediately by the person who prepared them.9
  18. Provide privacy for the patient. Have the patient remove clothing, as needed, depending on the injection site.
  19. Assemble the appropriate-size needles, syringes, and other administration supplies, as needed.
  20. Perform hand hygiene and don gloves.
  21. Select the appropriate site for injection based on the patient’s age, weight, muscle tissue mass, and medication volume and viscosity.
  22. Assist the patient to a comfortable position that is appropriate for the chosen injection site (e.g., sitting, lying flat, side-lying, prone).
    Rationale: A comfortable position reduces strain on the muscle and minimizes injection discomfort.
  23. Cleanse the site with alcohol or an antiseptic swab, per the organization’s practice. Allow the skin to dry completely. Optional: Use a vapocoolant spray (e.g., ethyl chloride) for pain relief just before injection.
    Rationale: A vapocoolant spray decreases pain at injection site.
  24. Administer the vaccine to the patient per the manufacturer’s instructions for use (Figure 1)Figure 1 (Figure 2)Figure 2 (Figure 3)Figure 3.
  25. Apply gentle pressure to the site; do not massage. Evaluate the site for bleeding and apply a bandage if needed.
    Rationale: Massage damages underlying tissue.
  26. Assist the patient to a comfortable position and have him or her replace clothing as needed.
  27. Discard the uncapped needle (or needle enclosed in the safety shield) and attached syringe into a puncture-proof and leakproof receptacle.
    Rationale: Discarding the uncapped needle helps prevent injury to the patient and health care team members. Recapping needles increases the risk for a needlestick injury. 10
  28. Monitor the patient for adverse and allergic reactions to the medication. Recognize and immediately treat dyspnea, wheezing, and circulatory collapse, which are signs of a severe anaphylactic reaction. Follow the organization’s practice for emergency response.
  29. Assess, treat, and reassess pain.
  30. Monitor for burning, numbness, or tingling at the injection site.
  31. Discard supplies, remove gloves, and perform hand hygiene.
  32. Document the procedure in the patient’s record.


  • Correct medication administration according to the six rights of medication safety
  • Acceptable level of comfort after injection
  • Patient able to explain purpose of vaccination
  • Desired effect of medication with no adverse reactions or signs of allergies


  1. Incorrect medication administration according to the six rights of medication safety
  2. Adverse reaction to the medication, with signs of urticaria, eczema, pruritus, wheezing, or dyspnea
  3. Patient complaints of localized pain, bleeding, or continued burning at injection site, indicating potential injury to nerve or vessels
  4. Unmanaged pain
  5. Patient unable to explain the purpose of vaccination


  • Vaccine name, dose, route, site, and time and date of administration
  • Patient’s response to medication, including any adverse reactions
  • Unexpected outcomes and related interventions
  • Patient education
  • Patient’s weight in kilograms per the organization’s practice


  • Children can be very anxious or fearful of needles. Assistance is sometimes necessary to hold the child and position him or her properly. Distraction, such as blowing bubbles and applying pressure at the injection site before giving the injection, may help alleviate the child’s anxiety.
  • If possible, a topical analgesic should be applied to the injection site with sufficient time allowed for peak action before the IM injection. A vapocoolant spray (e.g., ethyl chloride) may also be used just before injection to decrease pain. The health care team member should collaborate with the practitioner to obtain orders for pain prevention before injection.


  • Older adult patients may have decreased muscle mass, which reduces drug absorption from IM injections.
