LONDON -- The World Health Organization is recommending that swine flu be added to the regular flu vaccine next season.
WHO said in a statement Thursday that it held a meeting this week to decide which flu strains should be recommended to drug makers for their vaccines during the northern hemisphere's next flu season, which begins in the fall.
Flu vaccines have three virus strains -- which experts decide on after estimating which strains made the most people sick last season. Last year, the swine flu pandemic virus, or H1N1, emerged too late to be added to the regular flu vaccine and a new vaccine was needed.
