Sanofi Agrees to Help Make Doses of Moderna’s Covid Vaccine

Sanofi will help make up to 200 million doses of Moderna Inc.’s Covid-19 vaccine, the French drugmaker’s third agreement to throw its weight behind another company’s shot during the pandemic.

Sanofi will perform “fill-and-finish” work for Moderna’s messenger RNA shot in New Jersey starting in September, it said in a statement Monday. That entails putting already prepared vaccine solution into vials and packaging it -- a key step that Sanofi is also performing for the vaccines from the Pfizer Inc.-BioNTech SE alliance and Johnson & Johnson.
