The most important thing you need to know about the new swine flu vaccine is that it’s a new version of the influenza vaccine, which has been around for many years. It contains three different strains of the virus, and it’s designed to protect you from getting the flu. The vaccine is recommended for everyone 6 months of age and older, but children younger than 9 years old may need a different vaccine.
