Thousands of doses of COVID-19 vaccines are sitting in Collin County freezers waiting to be claimed.

“It’s difficult to fill the vaccination appointments that we have,” Collin County Administrator Bill Bilyeu told the Commissioners Court on April 19.

The day started with about 780 open appointments, and many of those went unclaimed, he said. More than 4,000 open appointments remained for the week, according to the county's website. Because the demand for vaccinations has slowed, the county has not requested more vaccine doses from the state.

“We have all of our second doses sitting in our freezers, and we have enough to handle our first doses for at least two or three weeks,” Bilyeu said.

Anyone age 16 and older in Texas is eligible for a COVID-19 vaccine. People interested in getting an appointment may sign up through the county’s online registration.
