Important Information:

This season, 2009 H1N1 vaccines are being made to protect against the 2009 H1N1 influenza virus (sometimes called “swine flu”). There are two kinds of 2009 H1N1 vaccines being produced: a 2009 H1N1 "flu shot" that is given with a needle, usually in the arm; and the 2009 H1N1 nasal spray flu vaccine given via a nasal sprayer. The same manufacturers who produce seasonal flu vaccines are producing 2009 H1N1 vaccines for use in the United States and the vaccines are being made in the same way that the seasonal vaccines are made.
