Shipments of Johnson & Johnson vaccine halted after human error ruins 15 million doses

Future shipments of the Johnson & Johnson COVID-19 vaccine have been halted while the Food and Drug Administration investigates, after human error at a manufacturing plant ruined 15 million doses, The New York Times reported Wednesday.

The plant in Baltimore is run by Emergent Biosolutions, and workers mixed up the ingredients in the vaccine, the Times reported.

The error does not affect doses of the Johnson & Johnson vaccine that have already been distributed, since those were made in the Netherlands, but it impacts future shipments of the vaccine, according to the Times.

The company in a statement acknowledged a batch of drugs “that did not meet quality standards” were identified at the Emergent Biosolutions plant, but did not specify how many what the problem was, or how the issue may impact its future deliveries.

J&J said it has met its commitment of delivering 20 million doses by today.
