J&J says 2 doses 100% effective against severe Covid

Johnson & Johnson says additional dose boosts Covid vaccine efficacy [See also J&J press release.] Johnson & Johnson said Tuesday that a large, global study showed its Covid-19 vaccine is more effective when given as a two-dose regimen, and that other data indicate the efficacy of the vaccine does not wane. The two-dose regimen prevented 75% of moderate to severe Covid cases in all countries where it was tested — and 94% of such cases in the United States, where fewer troublesome variants of the SARS-CoV-2 virus circulated at the time the trial was underway. Importantly, the two-dose regimen was 100% effective against severe disease. It appears J&J may use the data to argue in favor of making a booster broadly available to people who received the one-dose vaccine six months ago or more.
