Immunization Rates Dashboard

The dashboards below look at Wisconsin's routine immunization rates. It does not include influenza or COVID-19 vaccine information.

Summarizing the data

The longer people wait to get vaccinated the more they are at risk for getting sick from vaccine-preventable diseases.

  • Fewer people have gotten their routine vaccines in 2020 compared to the average number of people vaccinated in 2015-2019. The fewest amount of people got vaccinated between March 23 and May 11.
  • Of all the age groups, children aged 5 – 6 years had the biggest decline in the number of routine vaccines received.
  • The week many schools began (August 31) was the only week that routine immunization rates increased since the start of the pandemic.

 It will take many months of increased vaccination rates to catch-up everyone on the vaccinations they missed.


What data is being collected?

 Diseases that these vaccines prevent:

  • DTaP, Tdap, and Td - Diphtheria, Tetanus, and Pertussis (Whooping Cough)
  • MMR - Measles, Mumps, and Rubella
  • HepA and HepB - Hepatitis A and Hepatitis B
  • Hib - Haemophilus Influenzae B
  • HPV - Human Papillomavirus
  • IPV - Polio
  • MenACWY and MenB - Meningococcal disease (caused by serotypes A, C, W, Y, B)
  • MMR - Measles, Mumps, and Rubella
  • PCV13 and PPSV23 - Pneumococcal
  • Rotavirus - Rotavirus (childhood diarrhea)
  • Varicella - Chicken Pox

The Wisconsin Department of Health Services only reports on-time vaccinations based on the Centers for Disease Control and Prevention's (CDC) recommended immunization schedule. The graphs only include the following vaccines routinely given in these age groups:

  • 0 – 24 months old: DTaP, Td, HepA, HepB, Hib, IPV, MMR, PCV13, Rotavirus, and Varicella.
  • 5 – 6 years old: DTaP, HepA, HepB, IPV, MMR, and Varicella.
  • 13 – 18 years old: Tdap, Td, HPV, IPV, MenACWY, MenB, MMR, and Varicella.
  • 5 – 18 years old: DTaP, Tdap, Td, HepA, HepB, HPV, IPV, MenACWY, MenB, MMR, and Varicella.
  • 19 and older: Td, Tdap, PCV13, and PPSV23.

The vaccine that protects against Shingles was not included in this comparison because of recent changes in its vaccine schedule (number of doses needed) and limited availability of the vaccine.

We do not report vaccines administered outside of the age groups listed. If someone received a vaccine that they missed years ago, that vaccine is not counted in the graphs. Only including vaccines administered on-time in the recommended age groups makes it easier to compare this year’s data to the average of the past five years.

You may notice that children receive multiple doses of vaccines that protect them against Measles, Mumps, Rubella, Tetanus, Diphtheria, and Pertussis (Whooping Cough). This is because they need booster doses to boost their immunity that fades over time or to build immunity which will protect them against those diseases.


Total Number of Vaccines Administered


  • Vaccines administered - the number of vaccines that were given to people
  • Immunization rate - the percentage of a group that got the vaccines they need

These charts compare the number of vaccines* administered in Wisconsin each week to the average number of vaccines administered between 2015-2019. For example, by hovering over the two lines you can see how many vaccines were administered in the week of April 13, 2020, compared to the average number of vaccines administered in the week of April 13 in 2015-2019.

Percent Change of Immunization Rates

Percent change describes by what percent the number of vaccines* administered this year has changed compared to the five-year average (2015-2019). The percent change with positive numbers show that more people are getting vaccinated this year compared to the last five years. The percent change with negative numbers show that less people are getting vaccinated this year compared to the last five years.

For example, about 60% more 13- to 18-year-olds got vaccines in the week of August 31, 2020, than in the average week of August 31 in 2015-2019. But for almost all other weeks, less vaccines were given to people in all ages groups this year than in the average of 2015-2019.


*This data is counted by vaccine group. So, even though the MMR vaccine protects against three diseases, it counts as one vaccine administered because it is one vaccine group. But, one shot of Pentacel would actually be counted as three vaccines administered, since Pentacel includes three vaccine groups (DTaP, Hib and Polio).
