At a meeting to simplify the nation's covid vaccination policy, the FDA's panel of experts could agree on only one thing: Information is woefully lacking about how often different groups of Americans need to be vaccinated. That data gap has contributed to widespread skepticism, undervaccination, and ultimately unnecessary deaths from covid-19.
The committee voted unanimously Thursday to support the FDA's proposal for all vaccine-makers to adopt the same strain of the virus when making changes in their vaccines, and suggested they might meet in May or June to select a strain for the vaccines that would be rolled out this fall.
