Abstract

To defeat SIV, add a protein boost Despite 30 years of effort, no HIV-1 vaccine exists. Barouch et al. evaluated one promising strategy in rhesus macaques, a preclinical model commonly used to test potential HIV-1 vaccine candidates. They immunized monkeys with adenovirus-36 vectors engineered to express SIV (simian immunodeficiency virus) genes and then boosted them with a recombinant gp120 envelope glycoprotein (Env) from SIV. This regimen afforded greater protection than a strategy that instead used a viral vector–based boost. A parallel trial using a SHIV (simian/human immunodeficiency virus)–based vaccine and challenge model produced similar results. Whether this particular approach will be equally successful in humans remains to be tested. Science , this issue p. 320
