Aidsmap has two stories this morning on a vaccine trial using two types of vaccine that has produced a one-third reduction in HIV infection in a truly massive sample (over 16,000 participants). The study was conducted in Thailand and went forward against the advice of numerous scientists because one of the components of the trial produced a jump in infections in an earlier trial. Aidsmap outlines the controversy in An unpopular vaccine study produces surprising result.
Aidsmap also has a short write-up on the details of this first modestly effective vaccine trial in Vaccine reduces risk of HIV infection by one-third in large trial. The authors of the trial rightly call this an historic event in the course of HIV/AIDS.
UPDATE: Aidsmap has more reactions: Vaccine trial “is the beginning” of a new path of research, says US health chief.
