After a sluggish first month, the pace of coronavirus vaccinations is accelerating to the point that New York City and other places in the state expect to exhaust their supply of doses as early as next week, officials said on Friday, causing several health facilities to alter their immediate inoculation plans.
On Thursday, Mount Sinai Hospital, one of Manhattan’s largest facilities, canceled many upcoming vaccination appointments for older patients, saying the doses it had anticipated receiving were no longer likely to arrive.
Northwell Health, the largest health provider in the state, said it was not scheduling additional appointments for the next several days given the limited supply it had.
Elsewhere in New York, officials in at least one county said they had only enough doses to last through the weekend, echoing a similar sentiment by city officials.
Mayor Bill de Blasio said Friday on Brian Lehrer’s radio show that the city would run out of doses by next week.
“It makes no sense that we’re being starved of the capacity we need,” the mayor said.
Officials in New York State warned this week that they were growing increasingly worried about the supply, pleading with federal officials to increase the amount of doses they send every week. Gov. Andrew M. Cuomo has said the state receives only about 300,000 doses per week. About 100,000 of them go to New York City, Mr. de Blasio said on Friday.
Around the country, governors have expressed similar frustrations and made similar requests in the wake of federal health officials recommending that anyone over 65 be made eligible for vaccination, making tens of millions more eligible.
Until recently, New York City had been struggling to quickly administer the doses it had received, and a large backlog of doses had built up. But in recent days, the pace of vaccinations has picked up drastically because of expanded eligibility and because many new vaccination sites have opened over the last week, including several large government-run ones.
But as those new sites opened, the supply of vaccine doses that had been directed to some hospitals appeared to diminish. Many hospitals had only recently begun vaccinating their patients.
As of early Friday, New York City reported having received 800,500 doses, of which 337,518 vaccinations had been administered. But about 100,000 of the received doses were earmarked for nursing homes, city officials said, and others were set to be used as second doses for those who had already received their first shot. So, the actual number of doses available is less.
And the city has been increasing its daily vaccination rate. From Monday through Thursday of this week, the city administered nearly 120,000 doses.
“The increasing problem now is there is not enough supply of vaccine to keep up with the first appointments, let alone the second appointments,” Mr. de Blasio said on Friday.
