The New York Times reports workers at a Baltimore plant producing two COVID vaccines accidentally conflated the vaccines’ ingredients several weeks ago.

This miscue ruined 15 million doses of Johnson & Johnson’s vaccine and forced regulators to delay authorization of the plant’s production lines.

The plant is also manufacturing AstraZeneca’s shot.

“The mistake is a major embarrassment for Johnson & Johnson, whose one-dose vaccine has been credited with speeding up the national immunization program,” the Times reported.

Further shipments of the Johnson & Johnson vaccine were supposed to originate from the Baltimore plant, leaving supply of that particular injection in doubt.
