Les origines du SIDA

This documentary was very well done, and argued its case very well. I would like to have seen more on the genetics behind HIV and the known versions of SIV, but there are, apparently, not that many samples of SIV from the region, and new wildlife protection laws make it difficult to get more.

However... One of the other comments here asked why HIV did not appear early in the US if all vaccines were prepared using chimps. The documentary makes it clear that:

1) Most of the polio vaccines were prepared in a monkey serum. 2) Only the OPV used in the Congo was prepared using chimp serum, and it is from chimp SIV that we got HIV. Now there are some that claim SIV became HIV through hunting, but the OPV theory seems much more plausible.

As for why it's important to know about this now... We are still using animal serums for vaccines. We could use artificial serum, but it is more costly.
