"This has nothing to do with immigrants," he said. Instead, Henry said, Reynolds hasn't done enough to make sure Iowans are vaccinated. "For her to cry wolf about this doesn’t seem to make sense in light of the fact that she hasn’t done the work here in Iowa to make sure that everybody gets vaccinated," he said. About 49% of Iowa's 3.2 million residents are fully vaccinated, according to the CDC. Among adults, 61% are fully vaccinated and 65% have received at least one shot. Those figures have barely budged in recent weeks, as demand for the shots has plummeted. Reynolds said in April she hoped 75% of Iowa adults would be vaccinated by the end of June. Although Iowa fell short of that goal, the governor touted the state's vaccination numbers Tuesday, saying she was encouraged while also acknowledging the vaccination rate has slowed. COVID-19 infections are increasing nationwide because of the spread of the highly contagious delta variant of the virus. In Iowa, hospitalizations and case numbers have begun curving back up after relatively low case counts in June.
