Influenza Vaccine
Indications for Influenza Vaccine
Annual vaccination against influenza with an age-appropriate formulation is recommended for all people ≥ 6 months of age who do not have a contraindication. (SeeCDC: Child and Adolescent Immunization Schedule by AgeandCDC: Adult Immunization Schedule by Age.) Inactivated influenza vaccine (IIV)can be given to all people ≥ 6 months, including pregnant women. Recombinant influenza vaccine (RIV4)can be used in people aged 18 to 49 years. Live-attenuated influenza vaccine (LAIV)can be given to healthy people aged 2 to 49 years who are not pregnant and who do not have immunocompromising conditions. Safety of LAIV has not been established in people with disorders that predispose them to complications from influenza, including advanced lung disease or asthma. Adults ≥ 65 years should be given any one of the quadrivalent high-dose IIV, quadrivalent recombinant influenza vaccine, or quadrivalent adjuvanted IIV. If none of these are available, then any other age-appropriate influenza vaccine should be used. The high dose is recommended only for those ≥ 65 years. Health care workers who care for immunocompromised people (ie, those who require care in a protected environment) should be given IIV or RIV4 rather than LAIV (or they should avoid contact with the immunocompromised people for 7 days after getting the vaccine).
