(Radio Iowa) – State officials say they made a mathematical error when calculating how many Iowans over the age of 64 have had a Covid shot. A week ago, Governor Kim Reynolds announced 95 percent of Iowans over the age of 64 had received at least one dose of Covid vaccine. State officials now say that figure is 82 percent of the 65-plus. The error was made because Iowa Department of Public Health staff were counting doses, not people. That means people who got both doses of Covid vaccine were counted twice.

The state’s vaccination figures do not match the Centers for Disease Control’s data, which shows 76 percent of Iowans over the age of 64 have gotten at least a first dose of vaccine. Iowa officials say they’re using the latest U.S. Census data and the C-D-C is using averages based on total population. The C-D-C ranks Iowa tenth among the states in the percentage of residents over the age of 64 that have had at least one Covid shot.
