May 2nd, 2009 Swine Flu Vaccine Under Development

A vaccine for Swine Influenza will hopefully be available in several months.
The Swine Flu shot will be modeled after the flu shot which takes about six months to produce and distribute. Over 120 sites collect information on what strains are circulating year round. Twice a year, experts meet to determine which strains should be included in that season’s vaccine. Even with the “regular” flu, there is often not a perfect match between circulating strains and the distributed vaccine. However, people receiving a non-perfectly matched vaccine can still use it to help avoid getting sick, or at least not be sick for as long.
The U.S. still uses an egg-based production technique, in which selected strains of the influenza virus are grown in chicken eggs. One egg can only produce two doses of the vaccine at most. After this stage, government approval is required for the vaccine to be distributed. Although this is a lengthy process, officials hope a vaccine will be beneficial in the future.
