No, Delta doesn’t mean the vaccinated — or children — need to mask up again

With COVID cases in the country rising as the Delta variant spreads, the best thing political and public-health leaders can do is encourage the hesitant to get vaccinated. Yet many are instead undermining confidence in the shots, which have proven overwhelmingly effective against the new strain.

That’s the message sent by calling for — and in some cases instituting — a return to mask mandates, even for the vaxxed.

“Indoor mask use in NYC is falling — in delis, stores, subways, movie theaters etc. We need to reverse this trend,” tweeted Mark Levine (D-Manhattan), who chairs the City Council Health Committee. “It’s time to renew the indoor mask mandate, including for those who are vax’d.” He told The Post this week that he’ll lobby the state Health Department to do so.
