Moderna, AstraZeneca and J&J coronavirus shots rev up for NIH tests beginning in July: WSJ

As leading coronavirus vaccines make their way through early stages of human testing, the NIH is plotting much larger efficacy studies this summer. U.S. researchers plan to run phase 3 trials of vaccines from Moderna, AstraZeneca and Johnson & Johnson in the coming months, the Wall Street Journal reports.  The NIH intends to start a phase 3 trial of Moderna’s vaccine in July, followed by an August trial of AstraZeneca’s vaccine and a September study of Johnson & Johnson’s shot, a U.S. government researcher told the newspaper. All three of the shots are based on brand-new technologies, and they're all reportedly among finalists in the Operation Warp Speed program. Former FDA chief Scott Gottlieb has publicly questioned the picks, pointing out the team's reliance on new technologies. Johnson & Johnson has not previously disclosed any human testing for its vaccine and the company has previously said it’s aiming to enter human studies in September. But on Wednesday, the company said it's accelerating its timeline, with plans to start a phase 1/2a study in July.
