Covid-19 Vaccine Doses, Once in High Demand, Now Thrown Away

Governments, drugmakers and vaccination sites are discarding tens of millions of unused Covid-19 vaccine doses amid sagging demand, a sharp reversal from the early days of the mass-vaccination campaign, when doses were scarce.

Vaccine manufacturer Moderna Inc. recently discarded about 30 million doses of its Covid-19 shot after failing to find takers, while pharmacies and clinics have had to throw out unused doses from multi-dose vials from Moderna and Pfizer Inc. and its partner BioNTech SE that have a short shelf life once they are opened.
