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. (Advocate.com)
