A drug used to treat COVID-19 could be linked to mutations in the virus, scientists have said.
Molnupiravir works by causing mutations in the virus’s genetic information, or genome, many of which kill or harm the virus, reducing the amount of COVID in the body.
Used across the world to treat COVID, it was one of the first antivirals available to doctors during the pandemic.
But researchers who mapped virus mutations across global databases, have found that some COVID mutations linked to patients taking molnupiravir were very different to the usual mutations they saw, meaning it could lead to further infection.
Christopher Ruis, from the Department of Medicine at the University of Cambridge, said molnupiravir “belongs to
