(CNN)Three reports published Wednesday support the argument that people may need a booster dose of Pfizer's Covid-19 vaccine over time, and suggest such boosters would be safe.

The reports are part of a batch of data that will be discussed Friday by vaccine advisers to the US Food and Drug Administration. The FDA is considering a request by Pfizer to approve a third, booster dose of its vaccine for most people six months after they get their first two doses of vaccine.

But while the FDA clearly signaled it would grant emergency use authorization to Pfizer's and Moderna's vaccines last December, that it would grant EUA to Johnson & Johnson's vaccine in February and that it would fully approve Pfizer's vaccine last month, it was notably neutral about the question of booster doses for the general public.
