General Information About 2009 H1N1 Vaccines

This website is archived for historical purposes and is no longer being maintained or updated. For updated information on the current flu season, see the CDC Seasonal Flu website.

This season, vaccines to protect against the 2009 H1N1 virus (sometimes called “swine flu”) have been produced. Like seasonal flu vaccines, there are two kinds of 2009 H1N1 vaccines: a "flu shot "; that is given with a needle, usually in the arm; and a nasal spray flu vaccine. The same manufacturers that produce seasonal flu vaccines also produced the vaccines against the pandemic 2009 H1N1 virus in the same way that the seasonal vaccines are made. Vaccines to protect against 2009 H1N1 are widely available. CDC is now encouraging everyone to get vaccinated against 2009 H1N1, including people 65 years and older. Learn More…
