Johnson & Johnson COVID-19 vaccine batch fails quality check

A batch of Johnson & Johnson’s COVID-19 vaccine failed quality standards and can’t be used, the drug giant said late Wednesday.
The drugmaker didn’t say how many doses were lost, and it wasn’t clear how the problem would impact future deliveries.
A vaccine ingredient made by Emergent BioSolutions — one of about 10 companies that Johnson & Johnson is using to speed up manufacturing of its recently approved vaccine — did not meet quality standards, J&J said.
