A new study released Monday said Merck 's widely used antiviral Covid pill can cause mutations in the virus that occasionally spread to other people, raising questions about whether the drug has the potential to accelerate Covid's evolution.
Molnupiravir works by causing mutations in Covid's genetic information, which weakens or destroys the virus and reduces the amount of Covid in the body.
Researchers in the U.S. and U.K. specifically analyzed 15 million Covid genomes to see which mutations had occurred and when.
Based on data at the time, a spokesperson for Merck said it didn't believe molnupiravir was likely to contribute to Covid mutations.
The new study comes as Covid once again gains a stronger foothold in the U.S., primarily driven by newer strains of the virus.
