Lawmakers weigh removing hepatitis B from school immunization mandate as department warns of risk
Summary
Rep. Kelly Potenza introduced HB1719 to remove hepatitis B from the list of required childhood immunizations, aligning state policy with recent ACIP guidance; DHHS, pediatricians and nursing groups warned that removing the required birth dose could raise infection risk and outbreak costs, while sponsors argued for parental choice and targeted vaccination.
Representative Kelly Potenza returned to the House Health Committee to introduce HB1719, a bill to remove hepatitis B from New Hampshire’s list of immunizations required for school and child‑care entry. Potenza said the change would align state law with recent updates that place the infant birth dose into a shared clinical decision‑making category.
Why it matters: Potenza argued the change preserves parental choice and follows federal ACIP guidance. "This bill simply aligns state policy with that updated guidance," she told the committee, adding that the legislation does not ban hepatitis B vaccination and preserves access for infants at risk.
Public health experts emphasize infection risk and population benefits
Megan Hetty and Dr. Ben Chan of DHHS testified that removing the requirement would increase risk of preventable disease and could have fiscal consequences for schools and communities. Dr. Chan described hepatitis B as highly transmissible and noted long‑term clinical harms: “Hepatitis B virus is incredibly infectious,” he said, and infants infected early in life face very high risks of chronic infection and downstream liver disease.
Several pediatricians and the New Hampshire chapter of the American Academy of Pediatrics urged the committee to retain the birth‑dose requirement, noting that universal newborn vaccination since 1991 contributed to a large national decline in pediatric hepatitis B cases. Dr. Gwendolyn Gladstone said removing the requirement now would "be a disservice to the children in our state." The department also provided estimates for potential outbreak costs and emphasized that some pregnant women do not receive prenatal screening, which universal birth dosing addresses.
Supporters stress choice, recent federal changes
Supporters of HB1719, including some public witnesses and health‑care industry speakers, said ACIP’s reclassification of hepatitis B at the federal level supports a state policy that relies on targeted vaccination for infants at risk. Proponents argued targeted approaches like prenatal screening and vaccination of infants born to hepatitis‑B positive mothers can be effective in countries with robust screening systems.
What’s next: The committee will weigh expert recommendations, fiscal implications and the balance between universal prevention and parental choice. DHHS offered to supply additional data on the prevalence of hepatitis B in pregnant women and on the fiscal assumptions used in the bill’s analysis.
