US looking at joint production of Johnson and Johnson's Covid vaccine

The US is looking at joint production of Johnson and Johnson's Covid-19 vaccine in India and ways to help manufacturers like the Serum Institute of India (SII) to boost production, Daniel B Smith, the Charge D'Affaires of the US embassy, said on Tuesday. Smith also said that the efficacy of AstraZeneca's Covid-19 vaccine manufactured at a production facility in Baltimore is not yet clear and the Food and Drug Administration has not yet certified that the doses are available for anyone's use or for export.
Last month, the White House said that the US plans to share 60 million doses of AstraZeneca's vaccine globally as soon as they become available, and India expected a significant chunk of the total stockpile.
