vaccine

CHICAGO/FRANKFURT • The chief scientist of Johnson & Johnson said the company expects to produce up to three billion doses of its Covid-19 jab next year, after the European Union (EU) approved the one-shot vaccine on Thursday.

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