Immunization Rates

Vaccination rates are estimates of the number of people who have received particular vaccines, and are measured by population at national, state and local levels. The Immunization Program reviews data to assess immunization rates, identify populations at risk, and measure the impact of current initiatives. Aggregate child care and school immunization data are submitted annually and reported here. 

Each January the Vermont Immunization Program Annual Report highlights information about data trends.

National Immunization Survey

The National Immunization Surveys (NIS) are two annual telephone surveys, which assess immunization rates. The CDC’s National Center for Immunization and Respiratory Diseases sponsors and conducts the surveys.

2015-16 Aggregate Immunization Rates by School

To better understand the percentage of students in a school immunized for each required vaccine, Act 157 requires each school to make “aggregate immunization rates of the student body for each required vaccine” publicly available. Immunization rates for the entire school are reported here in alphabetical order. This spreadsheet is organized by school name, but may be ordered differently (eg. by supervisory union, highest to lowest rate, etc.) by clicking on the sort the top of each column.

2015-2016 Statewide Immunization Data

The Vermont Department of Health collects immunization data from all Vermont public and independent schools. This spreadsheet provides a picture of the immunization status of students entering kindergarten through twelfth grade.

Annual School Immunization Survey: Key Data Findings for 2015-16


  • 89.7% of children entering kindergarten had received all required vaccines; a 2% increase from the prior year.
  • Students may be provisionally admitted when they do not meet immunization requirements or have an exemption. Provisional admittance cannot exceed 6 months. The percentage of provisionally admitted children dropped to 4.6%, from 6.2% last school year. This is the lowest provisional admittance rate in eight years.
  • The non-medical (philosophic and religious) exemption rate dropped from 5.9% last school year to 5.5%. Philosophic exemptions, which will be eliminated in in July 2016, decreased from 5.8% last school year to 4.6%. There was an increase in religious exemptions from 0.1% last school year to 0.9%.

School-wide (K-12)

  • Over 93% of students (K-12) in Vermont public and independent schools were up-to-date on all required vaccines.
  • For all Vermont students (K-12) enrolled in public and independent schools, exemption rates were: medical 0.2%, religious 0.6% and philosophic 3.6%. Notably, religious exemptions increased at the same rate (0.4%) that philosophic exemptions decreased from the prior year.  
  • The percent of all Vermont students (K-12) that met the MMR vaccination requirements to protect against measles was 96.9%. The MMR vaccination rates for public and independent schools were 97.4% and 92.4%, respectively.

Vermont Immunization Registry Data Briefs

Vermont Immunization Registry Data Briefs are topical data summaries drawn from the Registry's aggregate data on vaccinations. The Immunization Program uses the data briefs to help to guide and inform public health action with the goal of improving vaccination rates and reducing vaccine-preventable disease.
