If Mr. Biden wants to encourage Americans to get the shots, he should change his attitude toward masks. Last week he said wearing masks in public is a “patriotic duty.” He continues to do so, even outdoors, even though he is vaccinated and therefore at almost no risk of either contracting the coronavirus or transmitting it to others. Federal mandates remain in place requiring masks in airports, national parks and public transit, among other places. Think about the messages that sends: If you get vaccinated, you’ll be afforded virtually no relief from the pandemic’s most persistent burden—the social and legal pressure to cover your face in public—which has lingered for more than a year. If you don’t get vaccinated, society will keep trying to protect you from infection by imposing discomfort on everyone. And the authorities, at least at the federal level, seem to be in no hurry for the pandemic to end.
