Instead, they received a Regeneron antibody product, which is used to treat Covid-19.
“The moment we were made aware of what had happened, we immediately acted to correct it, and we immediately revised and strengthened our protocols to improve our distribution process to prevent this from happening again,” said Major General James Hoyer, adjutant general of the West Virginia National Guard, in the statement.
The National Guard leads the planning and logistics for the distribution of the vaccine.
Boone County’s health department said it notified the 42 people and offered to give them the Covid-19 vaccine on Thursday.
Officials said it was an isolated incident but did not explain how the confusion took place when they came for further comment.
Boone County is located south of Charleston, the state capital.
The National Guard said the Department of Health and Human Resources would contact those who received the antibodies as a precaution.
Dr. Clay Marsh, the state’s czaar of Covid-19, said there were no risks to the 42 people.
“The product administered is antibodies that fight COVID-19,” Marsh said in the statement. “In fact, this product was the same that was given to President Trump when he became infected. While this injection is not harmful, it was substituted for the vaccine. But this incident provides our leadership team with an important opportunity to improve safety and vaccination process for every West Virginiaan. “
The National Guard said 7,855 were vaccinated in West Virginia on Wednesday.
