All Canadian infants should receive hepatitis B vaccinations, the National Advisory Committee on Immunization (NACI) has declared. The recommendation, issued in a recent update, expands the previous guidance that only high-risk infants should be vaccinated. Hepatitis B is a viral infection that attacks the liver and can lead to serious health complications, including chronic liver disease and liver cancer.
The new guidance is based on updated research showing that vaccinating all infants significantly reduces the risk of infection. The virus is transmitted through bodily fluids, and early vaccination is crucial to prevent long-term health issues. The recommendation applies to all newborns, regardless of birth weight or mode of delivery.
This change marks a shift in public health strategy. Previously, only infants at higher risk—such as those born to mothers with hepatitis B—were advised to receive the vaccine. Now, universal vaccination is considered essential for preventing the spread of the virus. The decision follows growing evidence that early immunization is both safe and effective.
Hepatitis B remains a significant public health concern in Canada, with approximately 1 in 100 people living with the virus. The new recommendation aims to reduce transmission rates and improve long-term health outcomes. Public health officials are now working to ensure healthcare providers are informed and equipped to implement the updated guidelines.
