UNDATED (WKOW) -- The World Health Organization says healthily people who catch swine flu don't need to take anitviral drugs to fight it.
The U.N. Agency made the announcement today saying doctors don't need to give tamiflu to healthy people with mild to moderate cases of the virus.
WHO says the anit-viral drug should be reserved for people in groups most at risk including children younger than five and adults over 65.
Meanwhile, U.S. officials continue tests on a new swine flu vaccine. Even though it appears to be safe, doctors wont know until next month whether it's effective against swine flu.
