Kindergarten Immunization Rates by School in Connecticut

State of Connecticut data provides school-level vaccination percentages for kindergarten students for the 2024-2025 academic year. The dataset covers six mandated vaccine series—polio, DTaP, MMR, hepatitis B, varicella, and hepatitis A—and tracks exemption rates. It is collected via an annual school immunization survey.

Use Cases

• Analyze geographic or school-level disparities in MMR or varicella vaccination percentages to identify public health intervention targets.
• Model the relationship between religious or medical exemption rates and overall 'All' vaccine series completion rates.
• Compare coverage trends across the six mandated vaccine series (polio, DTaP, MMR, hepatitis B, varicella, hepatitis A) to assess immunization program effectiveness.

Strengths

• Data is recent, covering the 2024-2025 academic year and last updated in August 2025.
• Includes detailed vaccination criteria for six distinct vaccine series, enabling precise interpretation of coverage rates.
• Explicitly reports both medical and religious exemption percentages, allowing for nuanced policy analysis.

Limitations

• Data for schools with fewer than 30 enrolled kindergarteners is suppressed, creating gaps in small-school analysis.
• Data is self-reported by schools and may contain discrepancies, as noted by the Immunization Program.
• The dataset does not contain individual student records, limiting analyses to aggregate school-level percentages.
