“After two years of analyzing the results of the largest AIDS vaccine clinical trial ever held — called RV144 — researchers say they have found two ways the immune system can respond, which could predict whether those inoculated will be protected or are more likely to become infected with HIV,” CNN’s health blog “The Chart” reports. The results were presented at the AIDS Vaccine 2011 conference being held this week in Bangkok, Thailand (Young, 9/13).
“An experimental malaria vaccine tested on children in Burkina Faso has shown ‘a high level of efficacy’ in protecting against the disease, a study published in” Thursday’s New England Journal of Medicine said, according to Agence France-Presse.
