Forty-two people received the antibody product, intramuscularly, at a vaccination clinic hosted by staff at the Boone County Health Department. The treatment, which was given Food and Drug Administration emergency use authorization in November, is normally given as an intravenous infusion.
Medical experts with the Joint Interagency Task Force do not believe there is any risk of harm to these 42 individuals, and all individuals who received the monoclonal antibody have been contacted or are in the process of being contacted, according to the West Virginia National Guard.
Regeneron is a drug cocktail consisting of antibodies designed to fight COVID-19. The drug was administered to President Donald Trump when he became ill with the virus.
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.
Vials for the treatment and the vaccine look somewhat similar, but are clearly labeled, as are the boxes that hold them. Both are kept in refrigeration before they are used.
