Not all locations administer vaccines to those under 18 and not all locations carry Pfizer. All individuals, regardless of their timeframe or reason for being in Wisconsin, are able to receive a COVID-19 vaccine. There should be no missed opportunity to vaccinate. The vaccine continues to be available at no cost and no ID or insurance is required. Visit to find a vaccine near you. When you do get vaccinated, please see these tips.

Experience with other vaccines has shown that the way our bodies develop protection, known as an immune response, after getting vaccinated and possible side effects of vaccines are generally the same when given alone or with other vaccines.

  • Largest CDC COVID-19 vaccine effectiveness study shows mRNA vaccines 94% effective
  • A new CDC study adds to the growing evidence showing that COVID-19 mRNA vaccines are performing as expected in the real world. The study showed that mRNA vaccines (Pfizer-BioNTech and Moderna) reduced the risk of getting sick with COVID-19 by 94% among health care personnel who were fully vaccinated and by 82% among those who were partially vaccinated. Data for the assessment came from a network covering 500,000 health care personnel across 33 sites in 25 U.S. states. Understanding vaccine effectiveness among health care personnel is important because they are at higher risk for exposure to COVID-19 through patient interactions.
