CDC Releases Influenza Vaccine Composition for 2017-2018
The U.S. Centers of Disease Control and Prevention (CDC) has released the composition of the 2017-2018 influenza vaccine. The composition of U.S. flu vaccines is reviewed annually and updated to match circulating flu viruses. Flu vaccines protect against the three or four viruses that research suggests will be most common.
For 2017-2018, three-component vaccines are recommended to contain:
- an A/Michigan/45/2015 (H1N1)pdm09-like virus
- an A/Hong Kong/4801/2014 (H3N2)-like virus
- a B/Brisbane/60/2008-like (B/Victoria lineage) virus
Four-component vaccines, which protect against a second lineage of B viruses, are recommended to be produced using the same viruses recommended for the trivalent vaccines, as well as a B/Phuket/3073/2013-like (B/Yamagata lineage) virus.
Health care providers are reminded that all persons 6 months and older should be vaccinated annually.
Vaccination to prevent influenza is particularly important for persons who are at increased risk for severe complications from influenza as well as those people who live with or care for persons at higher risk for influenza-related complications, including health care personnel.
