Despite substantial success in eliminating vaccine preventable diseases in the United States, some challenges remain. It was recognized in the early 2000s that pertussis (whooping cough) appeared to be making a comeback, and that protection appears to wane 5-10 years after vaccination. The Advisory Committee on Immunization Practices (ACIP) recommends that all individuals aged 11 years and older should receive a single dose of tetanus-diphtheria and acellular pertussis (Tdap) vaccine.

In 2011, a new school immunization requirement went into effect requiring one dose of Tdap vaccine for 7th grade school entry. During the 2017-2018 school year 95.7% of 7th grade students in Connecticut were vaccinated with Tdap and 97.3% were in compliance with vaccination requirements. Tdap vaccination rates have remained stable over the past 5 years.

Note: Compliancy is defined as the percent of students fully vaccinated divided by the subtotal of students excluding those with exemptions (subtotal =total number of students minus the number of exempt students).

These data are current as of October 2018.

What Works

Provision of Tdap vaccine at no cost to health care providers throughout the state to ensure adolescents have access to vaccine , educate medical personnel and the general public on the importance of Tdap vaccination in preventing pertussis disease and work with providers using the immunization registry to assure that all children in their practice are adequately immunized.

Action Plan

CT school immunization regulations require that all children entering 7th grade be vaccinated with a dose of Tdap vaccine prior to enrollment in a public or private school. The Immunization Program will continue to survey schools annually to monitor school compliance and enforcement of school immunization regulations to ensure children are meeting immunization requirements.

The Connecticut Vaccine Program is Connecticut’s childhood vaccination program. It ensures all children in the state get the vaccinations they need, when they need them, to stay healthy. The state buys vaccine at the lowest possible price through a government contract, and gives the vaccines at no cost to clinics, private doctors, and other health care providers. These providers then vaccinate children without charging patients for the cost of the vaccine (health care providers may still charge an administration fee). Without this program, some insurance companies may not cover the full cost of vaccine, making it too expensive for some families.
