News this month that an antiviral medication had proved effective against the coronavirus in a large clinical trial has brought new hope of a turning point in the pandemic: a not-too-distant future when a simple pill could keep infected people from dying or falling severely ill. The drug, molnupiravir, made by Merck, is easy to distribute and can be taken at home. The trial results showed it halved the risk of hospitalization and death among high-risk people early in their infections.
