Johnson & Johnson said it is sending additional experts to oversee production of its COVID-19 vaccine at a plant in Maryland where human error ruined millions of its one-dose vaccines. The plant is owned by a company that reportedly has been cited by US health officials for quality-control problems.
Emergent, a contract manufacturer based in Gaithersburg, Maryland, has been making the main ingredient for the pharmaceutical company's vaccine at one of its plants in Baltimore known as Bayview.
