Johnson & Johnson Says Its Booster Shot Provides Increased Protection From COVID-19

People who receive a Johnson & Johnson COVID-19 vaccine booster shot are better protected against the coronavirus for a longer period of time, according to the pharmaceutical company's latest trial results. The one-dose Johnson & Johnson vaccine has been found to be 66% protective against moderate and severe disease overall worldwide and 72% protective against such cases in the U.S. But when a person receives a booster shot two months after getting the pharmaceutical company's one-dose vaccine, the protection against COVID-19 increased to 94%. A booster shot at six months provided a 12-fold increase in antibodies.
