NEW BRUNSWICK, N.J. - Johnson & Johnson says a booster shot of its COVID-19 vaccine appears to produce "a rapid and robust" increase in antibodies needed to fight the coronavirus.
J&J says researchers saw increases in antibodies in people ages 18 to 55 and in study participants 65 and older who received a lower booster dose.
U.S. health officials announced last week plans to dispense COVID-19 booster shots to all Americans to shore up protection amid the surging delta variant of the virus. Officials say the protection against infections wanes over time among various vaccines but remains strong at preventing hospitalizations and deaths.
J&J says it is talking with regulators in both the U.S. and Europe about booster shots.
