Iowa entered the final stage of its COVID-19 vaccination schedule Monday, opening eligibility to all of the state's more than 2.3 million residents who are 16 or older.
With that expansion comes a new ratcheting up of demand against a still limited supply of vaccine doses.
Available Hy-Vee appointments filled up within about an hour of opening across the state on Monday morning, company spokesperson Christina Gayman said.
Carroll County Public Health Director Nicole Schwering wrote in an email that their 100 doses of the single-shot Johnson & Johnson vaccine were snatched up just as quickly. By the afternoon, half of their 300 first-dose shots of Moderna were likewise accounted for, she said.
