The Food and Drug Administration has asked Emergent BioSolutions to temporarily stop producing materials for Covid-19 vaccines while U.S. regulators investigate its plant in Baltimore responsible for ruining millions of Johnson & Johnson shots, Emergent said in a regulatory filing Monday.
It said the FDA initiated an inspection of the facility on April 12 and asked the company to halt manufacturing four days later, pending completion of the review and remediation. In a filing to the Securities and Exchange Commission, the company also said it quarantined all existing material manufactured at the facility.
