J&J Says Its Booster Shot Increases Immune Response

(New Brunswick, NJ) — Johnson & Johnson says a booster dose of its one-shot COVID vaccine is generating a huge increase in immune response.

The pharmaceutical company says a recent study shows people who received a booster shot six to eight months after their first dose of the J&J vaccine saw their antibodies increase nine times higher than after the first shot.

About 2,000 people in the U.S. and Europe received booster doses of J&J’s Janssen vaccine for the study. The CDC says about 14 million Americans have received the vaccine.
