WASHINGTON (AP) — The Food and Drug Administration is wrestling with how to decide on booster doses of the single-shot Johnson & Johnson COVID-19 vaccine.

Other manufacturers want to offer boosters six months after primary vaccination. But J&J proposed a range of times, from two months to six months.

In a review posted Wednesday, FDA scientists didn’t reach a firm conclusion, citing shortcomings with J&J’s data.

On Thursday and Friday, an FDA advisory panel will recommend whether to back boosters of both the J&J and Moderna vaccines.

An extra dose of Pfizer’s vaccine already is available to certain Americans.
