Marshfield Clinic Health System will require its employees to become fully vaccinated for COVID-19 by November 15.
The CEO said the vaccines are key to stopping the virus.
The decision to mandate was based on the increase in COVID-19 cases in Wisconsin and the delta variant.
In the last two weeks alone, the Health System saw COVID-19 hospitalizations triple.
Since the beginning of July, nearly every COVID-19 patient the Health System hospitalized was unvaccinated.
Marshfield Clinic says thousands of Health System employees, including nearly 100% of physicians, voluntarily received vaccinations.
It says the timing of the Health System’s COVID-19 vaccine mandate aligns with its annual required influenza vaccine process.
