| CDC Current and Recent Key Messages, February 26, 2010 2010 Influenza Vaccine - CDC's Advisory Committee on Immunization Practices (ACIP), a panel of immunization experts, voted February 24, 2010 to expand the recommendation for annual influenza vaccination to include all people aged 6 months and older. The expanded recommendation is to take effect in the 2010 - 2011 influenza season.
- The new recommendation seeks to remove barriers to influenza immunization and signals the importance of preventing influenza across the entire population. Prior to the vote, ACIP recommendations for seasonal influenza vaccination - which focused on vaccination of higher risk persons, children 6 months through 18 years of age and close contacts of higher risk persons - already applied to about 85 percent of the U.S. population.
- The composition of the Northern Hemisphere's 2010-2011 seasonal influenza was announced February 23rd at the FDA's Vaccines and Related Biological Products Advisory Committee (VRBPAC) meeting.
- The 2010 influenza vaccine will be trivalent (with three different vaccine viruses) and include an A/California/7/2009 (H1N1)-like virus, an A/Perth/16/2009 (H3N2)-like virus, and a B/Brisbane/60/2008-like virus. The H1N1 virus recommended for inclusion in the 2010-2011 seasonal influenza vaccine is the pandemic 2009 H1N1 virus and is the same virus used in the 2009 H1N1 monovalent vaccine.
- CDC monitors vaccine effectiveness. For more information about flu vaccine effectiveness, see http://www.cdc.gov/flu/about/qa/vaccineeffect.htm
