Hope for H1N1 vaccine

Researchers at a South Korean university say they have discovered a candidate strain for an H1N1 vaccine, though it has not yet been approved by health authorities in the United States or the World Health Organization.The strain is a genetically modified version of a live virus, and could lead to a vaccine against H1N1 commonly known as Swine Flu.Researchers around the world are racing to come up with a vaccine for the widespread virus, but the CDC and the WHO have said it could take up to six months between the time a virus appears to the time the vaccine is available to the public.
