Could Monkeys Lead to a Vaccine?

Researchers have discovered a vaccine that blocked simian immunodeficiency virus (HIV’s primate cousin, if you will) among rhesus macaque monkeys. Equally good: It also quickly resuppressed the viral loads of monkeys who already had SIV, according to a report in Frontiers in Immunology. What does it mean for you? Two human safety trials are being developed now, along the way to seeing if the vaccine could have the same impact on humans.
