The vaccine was designed to provoke the production of antibodies in subjects that would strip the gp120 protein off of the HIV viral particles, effectively disabling the virus so that it could not bind to or invade susceptible cells. Then, another group, infected with a second strain of HIV, A244, was discovered in 1995, and a revised, bivalent ...
