​Ad​ministration

​Registered nurses and medical assistants are the healthcare professionals most commonly administering immunizations. There are a few states that do not allow medical assistants to administer injections, so it is important to check state statutes. Many medical practices require that medical assistants be certified or registered and have graduated from an accredited medical assisting program to administer immunizations or any type of injections.

Administering immunizations correctly is a critical part of the healthcare professional's job. The flu vaccine is required to be administered either intramuscularly (IM), intradermally (in the case of Fluzone intradermal) or intranasally (in the case of nasal flu vaccine). Following the most current influenza vaccine policy from the American Academy of Pediatrics and the Centers for Disease Control and Prevention  is another important factor. It is important that healthcare professionals are knowledgeable and have been well-trained prior to administering immunizations. If immunizations are given improperly, the patient may not develop immunity.

Just prior to the delivery of flu vaccine to the office is a great time to freshen knowledge and skills on vaccine administration and safety. Remember the following:

  • Review the Vaccine Information Statements (VIS) for the current flu vaccine season

  • Review dosage recommendations, administration requirements and package inserts for the different flu vaccines

  • Review IM placement locations

    • On the thigh (vastus lateralis is the preferred muscle)—the preferred spot for infants and young children

    • Arm (Deltoid muscle)—older children and adults

    • Choose the right needle size

    • Usual choices in the pediatric setting are 5/8", 1", and 1 & 1/2"; ensure the needle length is sufficient to administer vaccine in the muscle mass, that's the goal. You don't want to merely hit deep into subcutaneous (SQ) tissue.

    • For infants up to age 1 year, a 1" needle is usually used in the vastus lateralis muscle of the upper thigh. Examine the 6-month child well; sometimes a 5/8" needle may be appropriate. The appropriate needle length, especially in infants, is very much patient dependent.

    • For toddlers and older children, needle length will vary based on injection site (vastus lateralis or deltoid) and weight of the patient (1" – 1.5").

  • For Injectable Flu vaccine

    • Insert the needle at a 90-degree angle quickly. Do not aspirate after needle insertion.

    • Remember multiple immunizations given on the same day should be given a minimum of 1" apart.

  • For Nasal Flu vaccine

    • Administer intranasally; sniffing is not required by the patient.

    • Each FluMist unit contains one dose with1/2 administered into each nostril.

  • For Intradermal Flu Vaccine (see administration guide)

    • Fluzone Intradermal vaccine is given in the upper arm—the same spot you would administer an IM vaccine

    • First shake the vial

    • Insert the needle perpendicular to the skin above the deltoid

    • Push the plunger to inject (do not aspirate)

    • Then remove the needle and dispose

  • Review Infection Control & Quality Control

    • Remind staff to wash hands prior to vaccine preparation and between each patient. Handwashing is the most important way to prevent the spread of infection. Handwashing is especially important during a busy flu-shot clinic when harried staff may be likely to forget.

    • Gloves should be worn if there is a likelihood that the person administering the vaccine might come into contact with body fluids or the person has open sores or cuts on the hands.

    • Always check expiration dates before drawing up the vaccine.

    • Document the vaccine administered in the patients chart accurately. See the Liability and Risk Management section of this document for details.

    • ​Give each patient the appropriate VIS for the current flu vaccine season before the vaccine is administered.​
