Dozens of people in West Virginia were mistakenly given Regeneron’s Covid-19 antibody treatment instead of the Moderna vaccine, the West Virginia National Guard announced Thursday.

The state’s National Guard said 42 people received the treatment, which is given intravenously, at a vaccination clinic staffed by the Boone County Health Department. The National Guard said it learned of the error on Wednesday.

Everyone who received the antibody treatment instead of the vaccine, which is given via a shot in the arm, have been contacted, Julie Miller, an administrator for the Boone County Health Department, told CNBC by email. She added that “we do not believe there is any risk of harm.”
