U.S. FDA proposes shift to annual COVID vaccine shots

The U.S. Food and Drug Administration also asked its panel of external advisers to consider the usage of two COVID vaccine shots a year for some young children, older adults and persons with compromised immunity. The FDA hopes annual immunization schedules may contribute to less complicated vaccine deployment and fewer vaccine administration errors, leading to improved vaccine coverage rates. Pfizer's primary vaccine doses for children and people involve three shots, with the third a bivalent shot given about two months later.
