Forty-two people in Boone County, in southwestern West Virginia, who were scheduled to receive the coronavirus vaccine on Wednesday were mistakenly injected with an experimental monoclonal antibody treatment instead, the West Virginia National Guard said on Thursday. None of the 42 recipients has developed any adverse effects so far, the Guard said in a statement. It is meant to be administered in an intravenous infusion, not in a direct injection like the vaccine. Maj. Gen. James Hoyer, the adjutant general of the West Virginia National Guard, said that the mix-up apparently happened during the delivery of a shipment of the Regeneron cocktail to a distribution hub, where the vials were placed among supplies of the Moderna vaccine. Workers at the hub then apparently included the treatment vials in a shipment of vaccine to Boone County.
