Workers at a Baltimore plant manufacturing two coronavirus
vaccines accidentally conflated the vaccines’ ingredients several
weeks ago, ruining about 15 million doses of Johnson & Johnson’s
vaccine and forcing regulators to delay authorization of the
plant’s production lines.
The plant is run by Emergent BioSolutions, a manufacturing partner
to both Johnson & Johnson and AstraZeneca. Federal officials
attributed the mistake to human error. […]
The mistake is a major embarrassment for Johnson & Johnson, whose
one-dose vaccine has been credited with speeding up the national
immunization program. It does not affect Johnson & Johnson doses
that are currently being delivered and used nationwide. All those
doses were produced in the Netherlands, where operations have been
fully approved by federal regulators.
