Are 1st world nations allowing the testing of man made viruses in Africa?

As suggested in the Movie "The Constant Gardener". Or as suggested by some that AIDS was infact created and possibly mistakenly released. I find it hard to believe that it spread from Chimpanzee to man but that's just me. I read a story on American scientists attempts to engineer a version of the bird flu that can me transmitted from human to human in order to develop a vaccine before it mutates naturally. This seems like a crazy thing to do but what do I know, they will probaby just develop a drug to mask the symptoms so people can survive with the virus for a long time. Maybe I am just cynical.
