School Immunization Survey Data

Required Immunizations for School and Child Care

Vaccination is a medical intervention with direct benefits to both individuals and communities. When a large percentage of a population is vaccinated, the entire community (vaccinated and unvaccinated) receives additional protection from vaccine preventable diseases. This concept, known as 'herd immunity,' is a primary justification for mandatory vaccination policies in the United States. By following the recommended schedule and fully immunizing children on time, parents protect their children against 14 vaccine preventable diseases. If a high enough percentage of children are vaccinated outbreaks can also be prevented. 

In the U.S., all states require children attending public school or state-licensed day care facilities to receive a series of vaccinations. Vaccination requirements for school and day care attendance are critical to ensuring high rates of vaccination. Linking vaccination with school attendance, which is also required by law, ensures that vaccines reach the greatest number of children. Schools are a prime venue for the transmission of vaccine-preventable disease, and active school-age children can further spread disease to their families and others with whom they interact.1

Specific vaccine requirements for school and child care vary by state. The Connecticut immunization laws and regulations can be found on the Department of Public Health’s Immunization Laws and Regulations web page. Each school and child care program is responsible for ensuring that attendees are in compliance with the vaccine requirements.

Immunization Survey

The school immunization survey measures the extent to which children in Connecticut are protected from vaccine-preventable diseases. Each year the Department of Public Health distributes an immunization survey to all Connecticut schools and licensed group day care homes and child care centers. On the survey, the total number of attendees who completed the required vaccine series, the number who failed to complete the required vaccine series, and the number of children with a religious or medical exemption are reported. This information is reported for all child care attendees on the child care survey and for all kindergarten and seventh grade students on the school survey. In addition, influenza vaccine receipt is surveyed for all preschool2 attendees. Individual vaccine information on each child is not collected; only total numbers are collected from each school and child care facility.

Typically survey results for the current school year will not be available until the summer or fall of the next school year.
