--A mix-up at a U.S. factory will delay distribution of the Johnson & Johnson Covid-19 vaccine, the New York Times reported.

--The NYT said that workers at the Baltimore plant had accidentally conflated the vaccine's ingredients weeks ago and ruined about 15 million doses of Johnson & Johnson's vaccine.

--The plant is run by Emergent BioSolutions, a manufacturing partner to Johnson & Johnson and AstraZeneca PLC, the NYT said.

--Johnson & Johnson vaccine doses currently being delivered and used nationwide were produced in the Netherlands and are not affected, the NYT reported, adding that all further shipments of the Johnson & Johnson vaccine were supposed to have come from the Baltimore plant and are now in question while the quality control issues are sorted out.

In after-hours trading, Johnson & Johnson shares were down 0.33% at $163.81, while Emergent Solutions' stock was down 4.85% at $88.40.
