A single dose of the AstraZeneca vaccine can protect older people, a study shows. California reaches a deal that encourages schools to reopen.
Tens of thousands of students walked into classrooms in Chicago public schools on Monday for the first time in nearly a year. Restaurants in Massachusetts were allowed to operate without capacity limits, and venues like roller skating rinks and movie theaters in most of the state opened with fewer restrictions. And South Carolina erased its limits on large gatherings.
Across the country, the first day of March brought a wave of reopenings and liftings of pandemic restrictions, signs that more Americans were tentatively emerging from months of isolation, even if not everyone agrees that the time is ripe.
There are plenty of reasons for optimism: Vaccinations have increased significantly in recent weeks, and daily reports of new coronavirus cases have fallen across the United States from their January peaks.
In Kentucky, all but a handful of school districts are now offering in-person classes, while the state races to vaccinate teachers as quickly as possible. Gov. Andy Beshear told reporters last week that the state’s falling infection statistics showed that immunizations were beginning to make an impact.
“It means vaccinations work,” he said. “We’re already seeing it. We’re seeing it in these numbers. It’s a really positive sign.”
Dr. Anthony S. Fauci, President Biden’s chief medical adviser for Covid-19, said at a news briefing on Monday that for small groups of people who have all been fully vaccinated, there was a low risk in gathering together at home. Activities beyond that, he said, would depend on data, modeling and “good clinical common sense,” adding that the Centers for Disease Control and Prevention would soon have guidance for what vaccinated people could safely do.
The positive signs come with caveats. Though the national statistics have improved drastically since January, they have plateaued in the last week or so, and the United States is still reporting more than 65,000 new cases a day on average — comparable to the peak of last summer’s surge, according to a New York Times database. The country is still averaging about 2,000 deaths per day, though deaths are a lagging indicator because it can take weeks for patients to die.
More contagious variants of the virus are circulating in the country, with the potential to push case counts upward again. Testing has fallen 30 percent in recent weeks, leaving experts worried about how quickly new outbreaks will be known. And millions of Americans are still waiting to be vaccinated.
Given all that, some experts worry that the reopenings are coming a bit too soon.
“We’re, hopefully, in between what I hope will be the last big wave, and the beginning of the period where I hope Covid will become very uncommon,” said Robert Horsburgh, an epidemiologist at the Boston University School of Public Health. “But we don’t know that. I’ve been advocating for us to just hang tight for four to six more weeks.”
The director of the C.D.C., Dr. Rochelle Walensky, said at the briefing on Monday that she was “really worried” about the rollbacks of restrictions in some states. She cautioned that with the decline in cases “stalling” and with variants spreading, “we stand to completely lose the hard-earned ground we have gained.”
And the plateauing case levels “must be taken extremely seriously,” Dr. Walensky warned at a briefing last week. She added: “I know people are tired; they want to get back to life, to normal. But we’re not there yet.”
After some counties in Washington State allowed movie theaters to reopen, Nick Butcher, 36, made up for lost time by attending screenings of the “Lord of the Rings” trilogy for three straight nights. He bought some M&Ms at the concession stand, sat distanced from others in the audience, and said he felt as though things were almost back to normal.
