COVID-19 Vaccine Update

Madison Medical Affiliates & Ascension are working together to vaccinate our patients & our community at several sites across SE Wisconsin. Please check our website for updates on eligibility & availability of the COVID-19 Vaccine.

  • Eligibility: Effective April 5th, the Wisconsin Department of Health Services (DHS) expanded vaccine eligibility to EVERYONE 16 and older. 
  • Availability: Due to decreased demand, Madison Medical is no longer offering new vaccine appointments at this time. Please visit to find an appointment in your area.
  • *IMPORTANT*: We will continue to monitor whether booster shots will be needed in the future. We will contact our patients if those are required.
