Vaccination sites operated by New York state will begin closing down this week.

“I think they’ve been a little slower,” said Dr. Harry Miller.

At this point, medical professionals like Miller at Four Seasons Pediatrics in Clifton Park are not surprised.

“People are more likely to want to get those vaccines at their primary care provider,” he said.

But Miller is wary as eligibility for young people is poised to expand.

“The question will be, how much of a demand it will be,” he said.

State officials said the vaccination sites at Aviation Mall in Queensbury will permanently close Thursday; the Crossgates Mall site in Albany County will close next Friday; and sites in Syracuse and Buffalo will close later this month.

“We have an ultra-cold freezer,” Miller said. “That allows us to store a vaccine for a prolonged period, and take it out as we need it.”

Miller said his office has been able to receive and store an ample supply of vaccines since children older than 5-years-old have been eligible.

“It ebbs and flows,” he said. “It depends on the rates of COVID. It will also depend on looking at when school is in session.”

But with an Food and Drug Administration (FDA) panel recommending Moderna’s vaccine for children even younger, Miller expects the demand to change swiftly.

“We would advocate that this is a safe, effective thing to do and to talk to their pediatrician,” he said.

He believes most of his colleagues will be able to handle a change in demand, but he does have concerns.

“Usually, we get a break where we’re going to do more well visits. We haven’t had that break,” he said. “I think there is a fatigue factor for a lot of docs.”

State Health Department officials said it's prepared to work with any offices that become overwhelmed by increased demand.

“I think they’re ready, prepared and want to do it,” Miller said.
