Immunization Program

Hepatitis B immune globulin (HBIG) at birth and hepatitis B vaccine series complete by 12 months of age for infants born to mothers with hepatitis B


Line Bar
Story Behind the Curve

Infants born to mothers who are hepatitis B positive have a 40% chance of becoming chronically infected with hepatitis B if they do not receive the appropriate post-exposure prophylaxis. This includes receipt of the first hepatitis B vaccine and the hepatitis B immune globulin (HBIG) within the first 12 hours of life, the second hepatitis B vaccine at 1-2 months of age, and the final hepatitis B vaccine at 6 months of age. During 2016, 90.2% of infants born to mothers with hepatitis B received HBIG at birth and completed the hepatitis B vaccine series by age 1. Connecticut has maintained a high completion rate, but this can fluctuate year-to-year depending on several factors such as infants moving out of the country or failure to return to the pediatrician for vaccinations.

These data are current as of December 2017.

What Works

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.

Pediatrician reminder-recall systems help to bring patients back in for vaccinations.

SHIP Strategies:

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.

Action Plan

Connecticut has a perinatal hepatitis B coordinator who identifies pregnant women with hepatitis B infection and notifies their obstetricians of the need for proper management of the infant. The coordinator also notifies the infant's pediatrician and tracks hepatitis B vaccine dates and post-vaccine serological testing to ensure that the baby is immune to hepatitis B. Parental education is also important and outreach to the mothers is also performed by the coordinator.

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.
