Merck’s Covid Antiviral Gets WHO Backing for High-Risk Patients

Merck & Co.’s Covid-19 antiviral pill was endorsed by a World Health Organization panel for patients in the early stages of disease who face high risk of hospitalization.

The WHO panel of international experts, which looked at data from six randomized clinical trials involving more than 4,000 patients, found a moderate certainty that Merck’s molnupiravir reduces the risk of hospital admission and recovery time. The effect on mortality wasn’t so clear. The decision was published Thursday in the BMJ medical journal.
