Hiv Gets A MakeoverThe slow pace of AIDS research can be pinned, in no small part, on something akin to the square-peg-round-hole conundrum. The HIV-1 virus won't replicate in monkey cells, so scientists use a monkey virus - known as SIVmac, or the macaque version of simian immunodeficiency virus - to test potential therapies and vaccines in animals. But therapies and vaccines that are effective on SIV don't necessarily translate into human success. Now, using a........Go to the Infectious disease blog (Added on 10/11/2006 5:17:53 AM)
