J&J to make up to three billion Covid-19 vaccines in 2022: chief scientist

Johnson & Johnson’s chief scientist said the company expects to produce up to 3 billion doses of its Covid-19 vaccine next year, after the European Union approved the one-shot immunisation on Thursday.

The company is bringing on three manufacturing plants to produce the key drug substance. It also will have seven plants globally that will handle final production steps and bottling into vials known as fill and finish.
