Axios Des Moines: Vaccination rates among Polk County’s government employees increased almost 9 percentage points since its vaccine-or-test mandate began in late September, according to records requested by Axios. At least 151 more of the county’s 1,573 employees have gotten fully vaccinated since the mandate took effect. Just over 77% of its workforce is now vaccinated. No resignations or terminations have resulted from the mandate, but one on-call security officer has been removed from scheduling until he complies with the requirements. Reprimands were initially made to multiple employees but they have since complied with weekly testing, county administrator John Norris told Axios.
