Mapping Pathways is a multi-national project to develop and nurture a research-driven, community-led global understanding of the emerging evidence base around the adoption of antiretroviral-based prevention strategies to end the HIV/AIDS epidemic. The evidence base is more than results from clinical trials - it must include stakeholder and community perspectives as well.

Clues emerge to explain first successful HIV vaccine trial

HIV-infected cellAfter decades of dashed hopes, AIDS vaccine developers are allowing themselves some cautious optimism. At a conference this week in Bangkok, Thailand, scientists reported molecular clues that help to explain the first-ever success of an HIV vaccine trial in humans (see 'Vaccine protects against HIV virus'). The results could point the way forward for designing future vaccines.

"You might say this is the most successful experiment we've had so far," says Adriano Boasso, an immunologist at Imperial College London.

The study analyzed clinical samples from a previous HIV vaccine trial of more than 16,000 people that has been dubbed the 'Thai trial' but is officially called RV144. In 2009, scientists leading that trial reported that, after three years, people who received the vaccine were about 30 percent less likely to contract HIV than those who got a placebo.

The modest results marked the first successful human trial of an AIDS vaccine, two years after the high-profile failure of a vaccine produced by the pharmaceutical company Merck. But Thai trial results also left many researchers scratching their heads.
