A month ago, U.S. Department of Health and Human Services (HHS) Secretary Katherine Sebelius put out a call asking you to raise awareness about how citizens can steel themselves against the H1N1 (aka, "swine flu") virus. Today, the HHS announced the 10 best citizen-created PSAs -- and you get to vote on the winner.

Take a look at the finalists' videos on the HHS YouTube channel or spin through this playlist:



Have your say about which ad you think is most effective in increasing knowledge and prevention of H1N1. The winner will receive $2500 and have his/her PSA aired on live television. Voting ends at midnight on September 8.
