New data shed light on efficacy of J&J’s single-dose vaccine against Covid-19
Scientists at the Food and Drug Administration said Wednesday that the single-shot Covid-19 vaccine developed by Johnson & Johnson is effective and prevents hospitalizations from the disease.
Johnson & Johnson also revealed new, encouraging data showing the vaccine may do a better-than-expected job at protecting patients against new variants of the virus that causes disease. At the same time, FDA experts said the company’s study, results of which were originally made public in a Jan. 29 press release, includes insufficient information to draw conclusions on efficacy in people older than 75.
