Vicious winter weather has snarled vaccine deliveries nationwide. The White House estimated that the weather had created a backlog of six million doses, and pleaded with local officials to extend hours at vaccination sites and schedule additional appointments.
The bad weather has slowed two vaccine shipping hubs — a FedEx center in Memphis and a UPS site in Louisville, Ky. And the Federal Emergency Management Agency said this week that more than 2,000 vaccine sites were in areas with power outages.
In Texas, where millions of residents lost power during this week’s powerful storm, state health officials said that more than 100,000 first doses and 300,000 second doses that were supposed to be delivered this week were still waiting to be shipped to Texas from out-of-state warehouses, citing data from the federal vaccine tracking system. The missed doses are expected to be delivered during the first half of next week.
In the Houston area, some vaccination sites began reopening at the end of this week. […]
Mr. de Blasio said on Friday that New York City had delayed scheduling up to 35,000 first dose appointments because of the shortage.
