Hepatitis B Infant Vaccinations, Birth Parent Screenings Decline

Oregon sees drop in newborns receiving hepatitis B vaccine at birth and fewer birth parents screened for the virus during pregnancy

Feb. 22, 2026 at 11:23pm

The number of newborns vaccinated at birth against hepatitis B has fallen slightly over the past four years in Oregon, according to a new dashboard from the Oregon Health Authority (OHA). Additionally, the number of birth parents screened for hepatitis B during pregnancy has also decreased. Health officials warn this 'dangerous combination' puts more babies at risk for the 'devastating effects of hepatitis B'.

Why it matters

Hepatitis B is a highly infectious virus that can lead to chronic liver disease, liver cancer, and even death if left untreated. Infants and young children are especially vulnerable, with up to 90% of those infected at birth developing chronic infection. The hepatitis B vaccine has been extremely successful at almost eliminating these illnesses, so declining vaccination rates could result in more children getting sick.

The details

In 2024, 82% of infants born statewide received the hepatitis B vaccine (HepB) birth dose, down from 86% in 2022. Statewide, the rate of birth parent hepatitis B screening was 94%, down from 96% two years earlier. Most Oregon hospitals reported screening rates exceeding 90% or higher in 2024, but some facilities reported rates below 80%. If a pregnant person is infected with hepatitis B, they can spread it to their newborn during childbirth, so screening during pregnancy is critical.

  • In 2024, 82% of infants born statewide received the HepB birth dose, down from 86% in 2022.
  • Statewide, the rate of birth parent hepatitis B screening was 94% in 2024, down from 96% two years earlier.

What they’re saying

“It's very concerning to see the number of babies getting a dose of hepatitis B vaccine after birth going down while the number of birth parents screened for hepatitis B is also decreasing.”

“This dangerous combination puts more babies at risk for the devastating effects of hepatitis B, which can impact them throughout their lifetimes. The hepatitis B vaccine has been extremely successful at almost eliminating these illnesses, and with decreasing vaccination rates, we will see more children get sick.”

What’s next

OHA's new Infant Hepatitis B Immunization dashboard will be updated annually every April. Data for 2025 will be available in the coming months.

The takeaway

The decline in hepatitis B vaccinations and birth parent screenings in Oregon is a concerning trend that could lead to more children becoming infected with this highly infectious and potentially deadly virus. Health officials are urging parents to ensure their newborns receive the hepatitis B vaccine at birth and for all pregnant individuals to be screened for the virus during pregnancy.
