Those who received the single-dose Johnson & Johnson coronavirus vaccine should get a booster shot as soon as it’s available to the public, health experts say.
“J&J is a very good vaccine. I also believe it’s probably a two-shot vaccine,” said Dr. Ashish Jha, the dean of the Brown University School of Public Health, CNN reported. “It’s really urgent that people get that second shot pretty quickly. Probably one is not enough.”
The Food and Drug Administration advisory committee recommended Friday that all adult J&J recipients should get a second vaccine dose at least two months later.
Experts say the second dose is necessary as the immunity from the initial shot wears off and the highly contagious delta variant continues to spread, CNN reported.
As of Monday, about 15 million doses of the J&J vaccine have been administered in the U.S. — or roughly 4% of the total number of coronavirus vaccine doses, according to Statista, a company that tracks market and consumer data.
