Get tips on reducing the spread of seasonal flu (influenza).

Annual flu shots are recommended for everyone

The Centers for Disease Control (CDC) recommends everyone 6 months of age and older to receive the seasonal flu vaccination. In February 2010, CDC's Advisory Committee on Immunization Practices (ACIP) voted in favor of "universal" influenza vaccination in the United States to protect as many people as possible against the flu.

About 2 weeks after vaccination, antibodies that provide protection against influenza virus infection develop in the body.

2015-2016 seasonal flu vaccine information

Flu vaccines are designed to protect against the main flu viruses that research suggests will be the most common during the upcoming season. Three kinds of flu viruses commonly circulate among people today: influenza A (H1N1) viruses, influenza A (H3N2) viruses, and influenza B viruses.

All of the 2015-2016 influenza vaccine is made to protect against the following three viruses:

  • an A/California/7/2009 (H1N1)pdm09-like virus
  • an A/Switzerland/9715293/2013 (H3N2)-like virus
  • a B/Phuket/3073/2013-like virus. (This is a B/Yamagata lineage virus)

Some of the 2015-2016 flu vaccine is quadrivalent vaccine and also protects against an additional B virus (B/Brisbane/60/2008-like virus). This is a B/Victoria lineage virus. Vaccines that give protection against three viruses are called trivalent vaccines. Vaccines that give protection against four viruses are called quadrivalent vaccines.
