On Thursday, September 24, 2009 initial results were released from an AIDS vaccine phase III trial in Thailand, which showed, for the first time, that the risk of HIV infection can be reduced by a vaccine (press coverage and AVAC statement below).

On October 20, 2009 at the annual AIDS Vaccine Conference, the investigators for the Thai prime-boost AIDS vaccine trial presented the results of additional data analyses. The presentation coincided with the publication of the results in the New England Journal of Medicine (links below). A webcast of the presentations made in Paris is available at the AIDS Vaccine 2009 webpage.
