2022-2023 Vaccine Exemption Rates by School (All Grades)

Metadata Updated: September 15, 2023

The annual pre-kindergarten (pre-K) through 12th grade school immunization survey collects school-level, grade-specific data on vaccine coverage and exemptions. The survey collects vaccination and exemption status data on children who entered the school system on or before a specified date during the fall semester. Individual vaccine information on each student is not collected.

This table shows the total percentage of vaccination exemptions (medical or religious) for each school. Data includes all schools who reported data students in any grade level Pre-K through twelve.

The values for schools with fewer than 30 enrolled students are suppressed, and those fields are left blank

Data Limitations and Considerations: • The school level data shown here are as tabulated and reported by schools and discrepancies may exist. • The Immunization Program identifies outliers and internally inconsistent data points and works with schools to resolve any data quality issues, when possible. • CT DPH cannot verify the accuracy of vaccine data for individual children or whether the documentation necessary to claim an exemption has been submitted. • Data are collected at the beginning of the school year, by which time vaccines are due. As the year progresses, immunization rates may increase as additional children receive required immunizations. Additionally, the student body is dynamic and as students arrive and leave school, the immunization rates are impacted. • Vaccine status is assessed on the level of the child and not on each vaccine. Once a child is listed as exempt, vaccination data is no longer collected in the survey for that child. Therefore, children with exemptions are not counted as vaccinated in the vaccine level assessments although they may have received some vaccines.
