They would become eligible four months after their first booster shot.

But they do work really well, even in three doses, to prevent hospitalization and death."
Wald is the medical director for UW Medicine's virology research clinic at Harborview, which is currently"What we really need is a new approach," said Wald, "a vaccine that's different and that would provide, I think, broader and longer lasting immunity so that we would not have to be getting boosters every six months."
