Americans may soon get a new Covid-19 vaccine option — shots made with a more tried-and-true technology than today’s versions. The big question: Why should they care?
After long delays, the Food and Drug Administration is expected to decide within weeks whether to authorize Novavax’s vaccine. It’s late in the pandemic for a new choice, with about three-quarters of U.S. adults already vaccinated.
But the company is hoping to find a niche among some of the unvaccinated millions who might agree to a more traditional kind of shot — a protein vaccine — and also to become a top choice for boosters, regardless of which type people got first. Only about half of vaccinated adults have gotten a booster.
