Yes, there were several manufacturers' vaccines approved for the 2009 Pandemic Swine Flu virus H1N1/09 by the FDA (US Food and Drug Administration) for use in the US.

For the 2010-2011 Flu season, the trivalent (contains three types of flu viruses) vaccine that was approved by the FDA contains the vaccine for H1N1 as well as the two other most likely to be circulating flu viruses.
