In the United States, government health advisers have decided to add protection against a Type B strain of the flu virus originally found in Australia to next season's flu vaccine. Although the Type B strain is not normally found in North America, the U.S. flu vaccine usually provides protection against the most common Type B strain circulating around the world. The advisory panel decided earlier this year to include protection against the same two Type A strains covered in this year's vaccine in the 2002-2003 shot; however, they delayed making a recommendation for the Type B strain until they had more data.
