"FDA Considers Annual Overhaul of Covid Vaccines to Combat Virus Variants"
The FDA is planning for an updated Covid vaccine to be rolled out this winter, with officials expecting to offer the shots annually, similar to the flu vaccine. The agency anticipates changes to the vaccine composition may be necessary based on the currently circulating strains of the virus, and the vaccine may need to be overhauled every year to provide protection against emerging variants. The FDA's Vaccines and Related Biological Products Advisory Committee will hold a meeting in May to discuss the updates, and vaccine companies like Pfizer and Moderna will be asked to update their shots accordingly.
