Science: New Anti-HIV Drug Could Work As Unconventional Vaccine

Exciting news today from Science Daily – a new anti-HIV drug candidate appears so potent it could work as an unconventional vaccine against the disease:

The study shows that the new drug candidate blocks every strain of HIV-1, HIV-2 and SIV (simian immunodeficiency virus) that has been isolated from humans or rhesus macaques, including the hardest-to-stop variants. It also protects against much-higher doses of virus than occur in most human transmission and does so for at least eight months after injection.

“Our compound is the broadest and most potent entry inhibitor described so far,” said Michael Farzan, a TSRI professor who led the effort. “Unlike antibodies, which fail to neutralize a large fraction of HIV-1 strains, our protein has been effective against all strains tested, raising the possibility it could offer an effective HIV vaccine alternative.”
