Mistake Delays Shipments Of Johnson & Johnson Vaccine


Shipments of Johnson & Johnson's coronavirus vaccine are on hold after a manufacturing mistake ruined millions of doses. Workers at a Baltimore plant that makes both Johnson & Johnson's vaccine and one by AstraZeneca accidentally mixed up the two companies' ingredients. That ruined about 15 million doses of Johnson & Johnson's vaccine. The Baltimore plant was supposed to start shipping the single dose vaccine, but that process is on hold after the mistake.
