An HIV vaccine blueprint

Science

The impact of therapies against HIV is limited by their cost, clinical infrastructure requirements, and patient adherence. An effective vaccine could be a more cost-effective and practical solution to control the spread of HIV. One approach to develop such a vaccine is to stimulate B cells of the immune system to produce broadly neutralizing antibodies (bnAbs) against the virus. On page 1261 of this issue, Skelly et al. report infecting rhesus macaques with a custom-made virus that was designed to expose a specific bnAb target. Within a year, most of the infected animals developed bnAbs. Eliciting similar bnAbs in humans would probably protect them against HIV infection.
