US Endorses Johnson & Johnson’s One-dose Covid-19 Vaccine, Says it Can be Stored Up to 3 Months

U.S. health advisers endorsed a one-dose COVID-19 vaccine from Johnson & Johnson on Friday, putting the nation on the cusp of adding an easier-to-use option to fight the pandemic. The acting head of the Food and Drug Administration said in a statement that the agency will move quickly to follow the recommendation, which would make J&J’s shot the third vaccine authorized for emergency use in the U.S. Vaccinations are picking up speed, but new supplies are urgently needed to stay ahead of a mutating virus that has killed more than 500,000 Americans.
