Influenza Vaccine Information
- The Influenza Vaccine Identification Guide from the CA Dept. of Public Health is a visual guide to all available US influenza vaccines.
- San Francisco providers who wish to order free, state-purchased influenza vaccine to administer to their patients: check our ordering page.
- Recommendations from the Advisory Committee on Immunization Practices (ACIP) for the 2019-20 flu season can be accessed here.
- Routine annual influenza vaccination of all persons aged 6 months and older continues to be recommended.
- No preferential recommendation is made for one influenza vaccine product over another for persons for whom more than one licensed, recommended product is otherwise appropriate.
- All 2019-20 trivalent (3-component) vaccines protect against these strains:
- A/Brisbane/02/2018 (H1N1)pdm09–like virus
- A/Kansas/14/2017 (H3N2)–like virus
- B/Colorado/60/2017-like virus (Victoria lineage)
- The quadrivalent (4-component) vaccine protects against the above 3 strains as well as a 4th strain, B/Phuket/3073/2013-like virus (Yamagata lineage).
- Live attenuated influenza vaccine (LAIV4 – FluMist Quadrivalent) is an option for healthy individuals ages 2 through 49 years who do not have a specific contraindication to receiving it.
- Children aged 6 months through 8 years who have previously received 2 or more doses of trivalent or quadrivalent influenza vaccine before July 1, 2019 require only 1 dose for 2019-20. Children in this age group who do not meet these criteria require 2 doses for the 2019-20 season. The interval between the 2 doses should be at least 4 weeks.
- Persons who report allergy to egg should receive annual seasonal flu vaccination. (Note, however that a previous severe allergic reaction to influenza vaccine, regardless of the component suspected of being responsible for the reaction, is a contraindication to future receipt of the vaccine.) Most available influenza vaccines are prepared by propagation of virus in embryonated eggs and might contain trace amounts of egg proteins, with two exceptions: RIV4 (Flublok Quadrivalent) and ccIIV4 (Flucelvax Quadrivalent).
