It would also bolster the two-pronged approach to the pandemic: treatment, by way of medication, and prevention, primarily through vaccinations.

Molnupiravir is also pending review at regulators in the U.S., Europe and elsewhere. The U.S. Food and Drug Administration announced last month it would convene a panel of independent experts to scrutinize the pill's safety and effectiveness in late November.

Initial supplies will be limited. Merck has said it can produce 10 million treatment courses through the end of the year, but much of that supply has already been purchased by governments worldwide.

In October, U.K. officials announced they secured 480,000 courses of molnupiravir and expected thousands of vulnerable Britons to have access to the treatment this winter via a national study.

“Today is a historic day for our country, as the UK is now the first country in the world to approve an antiviral that can be taken at home for COVID-19," said Britain's health secretary, Sajid Javid.

“We are working at pace across the government...
