“While many other vaccines target specific strains of HIV, the treatment that [Gallo] has developed takes a different approach. It attempts to block the virus before it can invade the body’s T-cells (a central component of the body’s immune system) and mutate, at which point it becomes invisible to the body’s immune system and much harder to treat. Should it prove successful, this vaccine would offer protection against a large class of viruses collectively known as “HIV-1.” [source]
Give it up, Gallo. I’m off to the betting shop to bet against him.
