    The Swiss Statement was a public policy salvo lobbed into the heart of the HIV world -- one that prompted a swift and intense backlash. People called it premature. People accused Vernazza of getting ahead of the science. Some demanded he produce data to prove there had been no transmissions. Others simply called him irresponsible. But it's not 2008 anymore.

  • PrEP, test-and-treat offer most cost-effective methods for HIV prevention

    Pre-exposure prophylaxis, or PrEP, and “test-and-treat” methods are both more cost-effective than the current strategy for the prevention of HIV transmission among men who have sex with men, according to researchers.
