(Ankeny, IA) -- Ankeny's school board has unanimously voted to comply with the federal COVID-19 vaccination requirement for employees. Employees must submit proof of vaccination or wear masks and provide weekly negative tests. The United States Supreme Court will hear challenges to the mandate on Friday. And while most SCOTUS analysts expect a swift ruling, it's unclear if that would occur prior to Monday's federal deadline. Ankeny's policy is in effect immediately.
