Refrigerated Flu Vaccine For Next Season
Refrigerated FluMist live intranasal influenza virus vaccine (Medlmmune) has been approved. The vaccine is used to prevent influenza in healthy children and adolescents 5 to 17 years of age and in healthy adults 18 to 49 years of age.
The new formulation, called CAIV-T (cold-adapted influenza vaccine-trivalent), can be stored in a refrigerator rather than in a freezer, as previously required.

FluMist has been marketed in a frozen formulation since its original FDA approval in 2003. The new formulation will be available for the 2007-2008 influenza season. Both the frozen and refrigerated forms are free of preservatives, including thimerosal.
FluMist should never be injected.
