White House promises more J&J COVID-19 shots after launch stalls

Johnson & Johnson should come close to hitting its target of delivering 20 million doses of its one-shot COVID-19 vaccine in March after its shipments stalled in recent weeks, a top White House official said on Monday, while declining to say how many will go out this week.

The company shipped four million shots in early March but its rollout has since stalled as facilities involved in the manufacturing await clearance from the U.S. Food and Drug Administration. J&J's COVID-19 vaccine was authorized by U.S. regulators in February, making it the third to be cleared for use in the United States and the first that requires just one injection for immunization.
