Radio Iowa You are here: Home Pharmacy leader: cancel unneeded vaccination appointments COVID-19 vaccine appointments are now open to all Iowans ages 16 and up, but as demand still far outpaces supply, it’s led some Iowans to make multiple appointments as they search for one closer to home. Kate Gainer, CEO of the Iowa Pharmacy Association, says when people don’t cancel unwanted appointments, it can lead to wasted doses. “It does create some workflow concerns. It creates concern over waste and having doses that have a very short window of time when they can be used,” Gainer says. “Those no-show appointments if not canceled, are difficult to get rescheduled.”
