Query: Contagion

A brilliant biologist and the hard working CDC are working around the clock to come up with a vaccine for the dying masses.They finally succeed but they're worried about getting the vaccine to the slaves. A Doctor says, "Homeland Security wants to know if we can put a vaccination in the water supply, like Fluoride, cure everyone at once".Near the end of the movie they explain everything to us. A bat drops an infected piece of fruit eaten by a pig who was slaughtered by a butcher. The butcher shakes hands with Gweneth Paltrow then Gweneth gives it to the guy she was having sex with in Chicago. Then Paltrow travels to Hong Kong and coughs on people there and comes home to her husband, Matt Damon. Damon has nice hair and perfect teeth and some sort of super built in immunity so he doesn't die. At the end of the movie they play a song by Bono.
