The Centers for Disease Control and Prevention announced no delays in the arrival of about 85.5 million flu vaccinations, which means that healthy people can get the shot sooner. Previously, healthy people between the ages of five and 49 years were asked to wait until after October to receive the vaccine due to shortages, but plentiful supplies are allowing earlier vaccination for everyone. The World Health Organization is urging all people to receive flu vaccinations to help doctors determine differentiate between influenza and severe acute respiratory syndrome. Meanwhile, this flu season is the first season that MedImmune's FluMist, which is jointly marketed with Wyeth, is on the market. The product allows people to receive flu vaccine via the nose rather than through an injection.
