NOTES

Key: IM = intramuscular; IN = intranasal

IM: For adults and older children, the recommended site of IM administration is the deltoid muscle. The preferred site for infants and young children is the anterolateral aspect of the thigh. Specific guidance regarding site and needle length for intramuscular administration can be found in ACIP’s General Recommendations on Immunization.

1 Persons with a history of egg allergy may receive any licensed, recommended influenza vaccine appropriate for recipient’s age and health status. Those who report having had reactions to egg involving symptoms other than urticaria (eg, angioedema, respiratory distress, lightheadedness, recurrent emesis), or who required epinephrine or another emergency medical intervention, should be vaccinated in an inpatient or outpatient medical setting, under the supervision of a healthcare provider who is able to recognize and manage severe allergic reactions, if a vaccine other than ccIIV4 or RIV4 is used.

2 May be administered by needle/syringe (≥6mos) or PharmaJet Stratis Needle-Free Injection System (18–64yrs only). Dose volume is 0.25mL for 6–35mos and 0.5mL for ≥3yrs.

3 Fluzone Quadrivalent 0.25mL prefilled syringes are not expected to be available for the 2021–2022 season. If a prefilled syringe is used for the 6–35mos age group, use the 0.5mL syringe.

Immunization providers should review FDA-approved prescribing information for 2021–2022 influenza vaccines for the most updated information, including (but not limited to) indications, contraindications, and precautions. Table listing reflects vaccines expected to be available during the 2021–2022 influenza season. This information is subject to change. For information on individual vaccines, see the product entries, contact the manufacturer, or call the National Immunization Hotline at (800) 232-4636.
