The agency’s vaccine review committee will meet on Friday to determine whether to endorse authorization of the company’s vaccine.
Documents released by the FDA today show that Johnson & Johnson’s Covid-19 vaccine is effective at preventing severe Covid-19 and hospitalizations relating to Covid-19. The Johnson & Johnson vaccine could be the third vaccine granted Emergency Use Authorization by the FDA, following vaccines made by Moderna and Pfizer/BioNTech. But the J&J vaccine is different from the already authorized mRNA vaccines in several ways. It works by using a genetically modified virus, called an adenovirus, to deliver DNA into cells.
