Sanford Health To Require Employees To Get COVID-19 Vaccination by Nov. 1 July 22, 2021 FARGO, N.D. — Sanford Health is requiring all 50,000 of its employees to be vaccinated against the coronavirus by November 1. Officials say more than 90% of clinicians and 70% of nurses within the health organization are already fully vaccinated. Exemptions will be made for medical or religious reasons. Sanford Health employees are already required to have several other vaccines including the annual flu shot. A Sanford Health official says although the decision has been under consideration for some time, resurgence of COVID-19 variants is one of the reasons for the mandate.
