Today is your last chance to enter for the $2,500 prize for flu PSAs through Flu.gov. It’s simple: produce a YouTube video of 15, 30, or 60 seconds in length, then pop it in the online submission form. A panel of celebrity judges will choose the top ten videos submitted, and those will then be presented to the YouTube community to vote on which video is the very best.
