AIDS has
killed more than 25 million people
worldwide but An experimental vaccine
has helped monkeys with a form of the
AIDS virus control the infection for more
than a year, suggesting it may lead to a
vaccine for people, US researchers have
said.The vaccine works by priming the
immune system to quickly attack the
HIV virus when it first enters the body, a
point at which the virus is most
vulnerable, US researchers said in a
study published in the journal Nature on
wednesday.
