Vaccination Coverage

Vaccination coverage, or the percent of people who have received particular vaccines, is measured at national, state and local levels. The Immunization Program reviews data to assess vaccination coverage, identify populations at risk and measure the impact of current initiatives.

Data collected in Vermont

Child Care Vaccination Coverage Data

Vermont law requires that all regulated center-based and family child care facilities submit annual data on immunization coverage. The 2017-2018 Immunization Survey was conducted through the Department for Children and Families (DCF) and the Child Development Division (CDD) in collaboration with the Department of Health Immunization Program.

Key Findings in 2018

In 2017-2018, 89% of all regulated child care programs completed the report – an increase from 87% in 2016-2017. The 982 programs reporting represent 17,023 children younger than age five (approximately 56% of all Vermont children that age) and not enrolled in school, receiving full or part-time care. A limitation of the data is that children may be enrolled in, and reported by, more than one child care program.

For children younger than five years of age enrolled in Vermont regulated child care programs:

  • 93.1% met all vaccine requirements for their age, an improvement of 0.5% from the prior year.
  • Vaccination coverage improved in 2017-2018 for all individual vaccines, with the greatest gain of 0.6% in DTaP since last year.
  • 4.0% were provisionally admitted (children that were not up-to-date on all required vaccines and did not have a signed exemption). In 2016-2017, the percentage was 4.8.
  • 2.7% had a religious exemption. The rate of non-medical exemptions was 4.3% in 2015-2016 when both religious and philosophical exemptions were allowed.
  • 0.2% have a medical exemption, the same percentage as school age children.
  • The vaccine with the lowest overall coverage rate was varicella (chickenpox) at 95.8%.
  • The vaccines with the highest overall coverage rate was measles, mumps and rubella (MMR) at 96.6%.

K-12 Public and Independent Schools Vaccination Coverage Data

The Vermont Department of Health collects vaccination coverage data from all Vermont public and independent schools. Data can be viewed on the following Excel spreadsheets:

Key Findings in 2018


  • The percentage of children entering kindergarten who received all required vaccines has increased from 89.6% in 2016-17 to 91.1% in 2017-18. This is a 10-year high.
  • The percentage of provisionally admitted kindergarten students (children that were not up-to-date on all required vaccines and did not have a signed exemption) decreased to 5.1%, from 6.4% in 2016-17
  • After decreasing in 2016-17, non-medical exemptions remained stable in 2017-18. The percentage of kindergarten students with a non-medical exemption (religious) was 3.6% in 2017-18. It was 3.7% in 2016-17.


  • 94.4% of all Vermont students enrolled in public and independent schools (K-12), received all required vaccines, the highest in the six years this data has been collected.
  • The percentage of all Vermont students (K-12), with an exemption was: 0.2% medical and 2.9% religious. Only 2.5% were provisionally admitted.
  • The percentage of students (K-12) that met the measles, mumps and rubella (MMR) vaccination requirement was 97.2%. The MMR vaccination series was completed by 97.6% and 93.6% of students in public and independent schools, respectively.

Historical School-Level Data

Colleges and Universities Vaccination Coverage Data

Vermont's Immunization Rule sets minimum vaccination requirements for attendance at colleges to protect students, staff and visitors against vaccine-preventable diseases.

Key Findings 2018

Statewide data submitted for the fall semester of 2017 show that overall 95.6% of college students are fully vaccinated, with over 97% meeting the requirement for two doses of measles, mumps and rubella (MMR) vaccine.

Since January 2018, there have been 3 confirmed and 9 probable cases of mumps reported to the Vermont Department of Health. All cases were associated with one of two outbreaks occurring at the University of Vermont and St. Michael’s College. No community cases were reported – cases were only reported among students attending one of the schools. The Health Department held vaccine clinics at both schools offering a 3rd MMR dose. For more information about mumps, check out our information on mumps.

Behavioral Risk Factor Surveillance System (Adults)

Vermont tracks adult health-related risk behaviors, chronic health conditions and use of preventive services using a telephone survey called the Behavioral Risk Factor Surveillance Survey (BRFSS).
