For the first time, more than three million people, on average, are receiving a Covid-19 vaccine each day in the United States, according to data from the Centers for Disease Control and Prevention. And on Saturday the country reported over 4 million doses in a single day for the first time.
The milestones reflect a steady increase in the capacity of states to deliver shots into arms. In early March, the nation surpassed an average of two million doses administered each day. The average hovered at around 800,000 doses a day in mid-January. And nearly a third of the United States population has received at least one dose of a Covid-19 vaccine as more states expand eligibility and production ramps up.
The news, which comes as President Biden enters the homestretch of his first 100 days in office and amid the general declines in new virus cases, deaths and hospitalizations since January, offers a sign of hope for a weary nation. But the average number of new reported cases has risen 19 percent over the past two weeks, and federal health officials say that complacency about the coronavirus could bring on another severe wave of infections.
“We have so much to look forward to, so much promise and potential of where we are, and so much reason for hope,” Dr. Rochelle Walensky, the director of the Centers for Disease Control and Prevention, said in an emotional plea to Americans this week. “But right now I’m scared.”
The rising vaccination rate has prompted some state officials to accelerate their rollout schedules. This week, Gov. Ned Lamont of Connecticut expanded access to people 16 and older, several days ahead of schedule. And Gov. Jared Polis of Colorado opened universal eligibility about two weeks earlier than planned.
“No more having to sort out if you’re in or if you’re out,” said Julie Willems Van Dijk, the deputy secretary of the Department of Health Services in Wisconsin, where anyone 16 or older will be eligible for a vaccine as of Monday. “It’s time to just move forward and get everybody with a shot in their arm.”
In another promising development, federal health officials said on Friday that Americans who are fully vaccinated against the coronavirus can travel “at low risk to themselves” within the United States and abroad.
But these days, most signs of hope are offset by peril.
Over the past week, there has been an average of 64,730 cases per day, an increase of 19 percent from two weeks earlier, according to a New York Times database. New deaths on average have declined, but they are still hovering around 900 a day. More than 960 were reported on Friday alone.
The C.D.C. predicted this week that the number of new Covid-19 cases per week in the United States would “remain stable or have an uncertain trend” over the next four weeks, and that weekly case numbers could be as high as about 700,000 even in late April.
Cases are already increasing significantly in many states, particularly…
