Even moderately
effective HIV vaccine useful?

A report released by the New York City-based International AIDS Vaccine Initiative says that even a vaccine that is only moderately effective at preventing HIV infections could still reduce the number of new HIV cases worldwide by one third. The report, titled "Estimating the Global Impact of an AIDS Vaccine," also says that any approved HIV vaccine must be used in conjunction with other HIV prevention methods, like condom use and needle exchange programs, to maximize its potential in slowing the spread of the disease.
