A government advisory panel is meeting Thursday to determine if any restrictions are needed for the Johnson & Johnson COVID-19 vaccine because of rare but serious blood clots.

A strange clotting problem prompted the U.S. to temporarily halt the single-dose J&J shots last April while scientists investigated. Eventually regulators decided the benefits of a one-and-done vaccine outweighed what was considered a very rare risk -- as long as recipients were warned.
