Some states will begin administering COVID-19 vaccines to nursing home residents this week, US officials said Monday.

US Gen. Gustave Perna said at a press conference alongside Health and Human Services Secretary Alex Azar, “We know that several states have already established and are going into long-term care facilities, they’ll go in there this week.

“Allocations for vaccines went out to the states, to the locations that they directed, and they are identifying in those populations who is first,” said the general, who is helping to oversee the nationwide distribution of coronavirus vaccines, which began being shipped Sunday and administered Monday, focusing on front-line health care workers.

Perna said that by next Monday, more than 1,100 nursing homes and long-term rehab centers in the country will begin inoculating their residents.

New York is among the states starting nursing home inoculations Dec. 21.

The Empire State’s nursing homes suffered a devastating blow under a directive issued by Gov. Andrew Cuomo at the height of the pandemic in the spring that said the sites could not bar the admission or readmission of someone based on a positive COVID test.
