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.

Child Care - Annual Immunization Survey

Vermont law requires that all regulated center-based and family child care facilities submit an annual immunization report to the Health Department.  The 2016-17 Immunization Survey was conducted through the Department for Children and Families Child Development Division (CDD), in collaboration with the Health Department Immunization Program.  In 2016-17, 87% of all regulated child care programs completed the report – an increase from 65% reporting the prior year.

The 1,053 programs reporting represent 17,477 children younger than age five (approximately 57% 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.

Immunization rates for licensed child care facilities can be viewed here. This spreadsheet is organized by the child care facility name, but may be ordered differently (eg. by town, highest to lowest rate, etc.) by first clicking on the button, and then sorted using the arrows at the top of each column.

Annual Child Care Immunization Survey: Key Data Findings for 2016-17

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

  • 92.6% met all vaccine requirements for their age, at the time of the survey.
  • 4.8% were provisionally admitted – these children were not up-to-date on all required vaccines and did not have a signed exemption. 
  • 2.4% 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.
  • 0.1% have a medical exemption. The same rate as in 2015-16.
  • The vaccine with the lowest overall coverage rate was varicella (chickenpox) at 95.6%.
  • The vaccines with the highest overall coverage rate were Hib and MMR at 96.4%.

2016-2017 Aggregate Immunization Rates by School

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.

2016-2017 Statewide Immunization Data

Annual School Immunization Survey: Key Data Findings for 2016-17


  • The percentage of children entering kindergarten who received all required vaccines is stable at 89.6% (a decrease of 0.1% from 2015-16)
  • 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 increased to 6.4%, from 4.6% last school year.  A contributing factor to this change may be that more students are in the process of getting caught up on required vaccines, after the elimination of philosophical exemption.  
  • Non-medical exemptions have decreased.  The percentage of kindergarten students with a non-medical exemption decreased from 5.5% (religious and philosophic) in 2015-16 to 3.7% (religious only) in 2016-17. 

School-wide (K-12)

  • 93.8% of all Vermont students enrolled in public and independent schools (K-12), received all required vaccines.  This is the highest rate in the last five years. 
  • The percentage of all Vermont students (K-12), with an exemption was: 0.2% medical and 3.0% religious (non-medical).  In the previous year, the percentage of students with a non-medical exemption (religious and philosophical) was 4.2%.  
  • The percentage of students (K-12) that met the MMR vaccination requirement to protect against measles was 97.0%.  The MMR vaccination series was completed by 97.6% and 92.6% of students in public and independent schools, respectively.

Historical School-Level Data

Colleges and Universities - Annual Immunization Report

Vermont's Immunization Rule sets minimum immunization requirements for attendance at colleges to protect students, staff, and visitors against vaccine-preventable diseases. Contagious diseases always cause worry on college campuses, where students are in very close physical proximity in classes and in dormitories. Data submitted for the fall semester of 2016 show that overall 95.9% of college students are fully vaccinated, with over 98% meeting the requirement for two doses of measles, mumps and rubella 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.
