Vaccination Coverage

Vaccination coverage is the estimated percent 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 vaccination coverage, identify populations at risk, and measures the impact of current initiatives. Aggregate child care and school vaccination data are submitted annually and reported here. 

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

The Centers for Disease Control and Prevention (CDC) provides an annual report on Seasonal Flu Vaccination Coverage by Age Group and Season

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.

Child Care - Annual Immunization Survey

Vermont law requires that all regulated center-based and family child care facilities submit an annual Health Department survey on immunization coverage.  The 2017-18 Immunization Survey was conducted through the Department for Children and Families, Child Development Division (CDD), in collaboration with the Health Department Immunization Program.  In 2017-18, 89% of all regulated child care programs completed the report – an increase from 87% in 2016-17.

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.

Vaccination coverage for licensed child care facilities can be viewed here.

Key Findings

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

  • Vaccination coverage improved in 2017-18 for all individual vaccines, with the greatest gain of 0.6% in DTaP since last year.
  • 93.1% met all vaccine requirements for their age, at the time of the survey, an improvement of 0.5% from the prior year.
  • 4.0% were provisionally admitted – these children were not up-to-date on all required vaccines and did not have a signed exemption. In 2016-17 the percentage was 4.8. 
  • 2.7% had a non-medical (religious) exemption.  The rate of non-medical exemptions was 4.3% in 2015-16 when both religious and philosophical non-medical 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 MMR at 96.6%.  

Annual immunization coverage data for each licensed child care facility, and total immunization coverage for all regulated child care programs (combined and by program type), are posted on the Health Department website. This fulfills the legislative requirement that coverage data is publicly available.

Annual School Immunization Survey: Key Data Findings for 2017-18


  • 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.
  • Students may be provisionally admitted for up to six months if they haven’t met state immunization requirements or do not have an exemption. The percentage of provisionally admitted kindergarten students 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. 

School-wide (K-12)

  • 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 (non-medical).  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 - Annual Immunization Report

Vermont's Immunization Rule sets minimum vaccination requirements for attendance at colleges to protect students, staff, and visitors against vaccine-preventable diseases. 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. High vaccination coverage at both institutions likely prevented further transmission.

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.

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.
