An undisclosed number of Johnson & Johnson COVID-19 vaccines have been pulled after a batch failed quality control, the drugmaker said on March 31.

“This quality control process identified one batch of drug substance that did not meet quality standards at Emergent Biosolutions, a site not yet authorized to manufacture drug substance for our COVID-19 vaccine. This batch was never advanced to the filling and finishing stages of our manufacturing process,” Johnson & Johnson said in a statement.
