The birth dose of hepatitis B protects infants from acquiring hepatitis B through contact with an infected mother, household member, or caregiver. Infants and young children are at the greatest risk of developing chronic hepatitis; 90% of infants infected with Hepatitis B will remain chronically infected. The Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC), the American Academy of Pediatrics, the American Academy of Family Physicians, and the American College of Obstetricians and Gynecologists recommend that the first dose of hepatitis B vaccine be administered within 24 hours of birth for every newborn in the United States.
CT immunization information system data were used to determine the percentage of newborns that were administered hepatitis B vaccine prior to hospital discharge. During 2016-2017 several hospitals experienced significant drops in their hepatitis B birth dose rates due to data quality issues related to the introduction of the new facility worksheet for the state vital record system (ConnVRS). DPH Immunization Program and Vital Records staff worked with hospital birth registrars to address these issues. Note - The estimates for 2021 measures the percentage who had hepatitis B vaccine administered by the end of the first full day after birth.
These data are current as of Feb 2023.

Universal hepatitis B vaccination of all newborns before discharge acts as a safety net for babies whose mothers were not tested for hepatitis B or whose results were not available at the time of birth.
Universal access to hepatitis B vaccine at no cost to patients to help minimize any financial roadblocks to vaccination that families may encounter.

Assure costs of vaccines/administration for all ages are covered by all insurers
Maintain and expand access to Advisory Committee on Immunization Practices (ACIP) recommended vaccines for children
Maintain and enhance Connecticut immunization registry, including across lifespan; implement comprehensive reminder/recall systems.
Use new and existing data systems to measure vaccine coverage among populations to identify disparities and target vaccine strategies.
The Perinatal Hepatitis B Coordinator and Immunization Action Plan (IAP) area coordinators encourage a high hepatitis B birth dose via hospital education. They also promote the Immunization Action Coalition (IAC) Hepatitis B Birth Dose Honor Roll, which hospitals can apply for if their birth dose rate is 90% or greater.
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 vaccines, making it too expensive for some families. Hepatitis B vaccine is available to newborns in hospitals and all children 0-18 years of age at no cost through the Connecticut Vaccine Program.
