J&J Covid vaccine manufacturing halted at plant that ruined doses

The US Food and Drug Administration requested that production of the Johnson & Johnson coronavirus vaccine be halted at a factory that previously reportedly ruined about 15 million doses of the shot. The pharmaceutical giant told AFP at the end of March it had identified a batch of doses at a plant in Baltimore run by Emergent BioSolutions "that did not meet quality standards," but did not confirm the specific number affected.
