Mississippi's state health officer, Dr. Thomas Dobbs, said the partnership "has been a fiasco."
The state has committed 90,000 vaccine doses to the effort, but the pharmacies had administered only 5% of those shots as of Thursday, Dobbs said. Pharmacy officials told him they're having trouble finding enough people to staff the program.
Dobbs pointed to neighboring Alabama and Louisiana, which he says are vaccinating long-term care residents at four times the rate of Mississippi.
"We're getting a lot of angry people because it's going so slowly, and we're unhappy too," he said.
Many of the nursing homes that have successfully vaccinated willing residents and staff members are doing so without federal help.
