AIDSVAX


AIDSVAX

A vaccine produced by VaxGen which failed to protect those receiving the vaccine from developing AIDS, although some data suggested that it may benefit African Americans. VaxGen has continued to expand the trials. The results of the Phase II trials were underwhelming, so VaxGen piggybacked it with the Aventis-Pasteur vaccine, ALVAC-HIV. Data from the combination vaccine, ALVAC-AIDSVAX B/E, has shown an efficacy ranging from 26 to 31% (N Engl J Med 2009; 361: 23, 2209-2220).
