American adults who haven’t yet gotten vaccinated against COVID-19 may soon get another choice, as advisers to the Food and Drug Administration on Tuesday backed a more traditional type of shot.

Novavax shots are already available in Australia, Canada, parts of Europe and multiple other countries, either for initial vaccinations or as mix-and-match boosters. But U.S. clearance is a key hurdle for the Maryland-based company.
