Since the COVID-19 vaccine rollout began last year, at least 10,128 doses have been damaged or discarded in Ohio.
The doses were unusable for a variety of reasons, said Alicia Shoults, spokeswoman for the Ohio Department of Health, via email.
Included in the list are doses that expired for lack of demand, accidents such as vaccine vials that may have broken during shipping and failure to be stored or shipped at adequate temperatures, Shoults said.
The Pfizer vaccine has to be stored at near-arctic temperatures while the Moderna vaccine can be kept in a freezer and the Johnson & Johnson shot is refrigerated.
