The vaccinated can now go maskless. (Mostly.) Some people are looking with horror at this new recommendation from the Centers for Disease Control, while others are reacting with relief. The scientific evidence is pretty clear: There’s powerful data showing that vaccines prevent not just symptomatic Covid-19, but also curb the spread of the virus.

Some of the fearful reactions might be driven by people getting stuck on earlier reports that the clinical trials didn’t do enough to test whether the vaccines cut down on transmission. But a lot has changed since then.
