Influenza Vaccine

All persons 6 months of age or older should receive influenza vaccination annually. There are a few different influenza vaccine formulations.

Inactivated influenza vaccine (IIV) can be administered to nearly all adults except those with severe allergic reaction (eg, anaphylaxis) after a previous dose of any influenza or to a vaccine component, including egg protein. Persons who experience only hives with exposure to eggs may receive recombinant influenza vaccine (RIV) if they are aged 18-49 years; or, with additional safety precautions, they may receive IIV. RIV (Flublok®) is available in the United States; it contains no egg protein and can be used in persons with any severity of egg allergy.

Healthy adults aged 2-49 years without allergy to eggs or influenza vaccine components have the option to receive the live-attenuated influenza vaccine (LAIV) if they do not want an injected vaccine. Intradermal and high-dose injectable influenza vaccines are also available for selected adults.
