Waiting six months instead of two months boosts antibody levels even more by twelvefold versus just four- to sixfold. STEIN: The company says additional research shows that waiting longer for that second shot could provide even better protection. He worked with Johnson & Johnson.ĭAN BAROUCH: This is the first data showing that a second dose increases effectiveness in terms of actual prevention of disease. I talked about this with Dan Barouch at Harvard. The company says giving people a second jab two months after the first looks like it can boost protection against moderate to severe disease from about 75%, where it is right now, to about 100%.
STEIN: Early this morning, Johnson & Johnson released data that the company says supports the idea that a second shot can provide people with even stronger protection against getting really sick. But now this update from Johnson & Johnson - what's the latest? Joining us now with the details is NPR health correspondent Rob Stein.įADEL: So all the news lately about boosters has been about another Pfizer shot. That's according to new data released by the company today. Turns out a second shot of the J&J vaccine significantly reduces the risk of getting severely ill.
