Reminder: Japanese encephalitis vaccination

This mosquito season, people travelling to regions where Japanese encephalitis virus (JEV) is present should take precautions to be protected. Protection may include physical barriers (e.g. long, loose clothing, DEET, mosquito nets) and vaccination. 

Japanese encephalitis is a leading cause of vaccine-preventable encephalitis in Asia and the Western Pacific. 

Vaccination is recommended for those at highest risk of exposure so JEV. Some individuals are prioritised and funded to receive vaccines through state-led programs.

BBC: US panel votes to end recommending hepatitis B vaccine for all newborns

The US-based Advisory Committee on Immunization Practices (ACIP) now recommends individual-based decision-making for hepatitis B vaccination in babies born to mothers who have tested negative for liver infection. 

According to BBC, public health experts worry ACIP’s decision will raise unfounded safety concerns about the vaccine. 

Up to 90% of those infected with hepatitis B in infancy will go on to develop chronic infection. Chronic hepatitis B can lead to cirrhosis, liver failure, liver cancer and death. There is no cure for chronic hepatitis B.

On 11 December 2025, the 澳大利亚免疫技术咨询小组 (ATAGI) released a statement on the importance and safety of hepatitis B vaccination at birth.

ATAGI outlines reasons for their birth dose recommendations, including: 

• Screening during pregnancy does not always occur 
• The pregnant person may become infected after screening 
• Transmission from another household member to the baby may occur 
• Babies infected at birth have about a 90% chance of developing chronic hepatitis B

Unbiased Science: Evidence, Not Guesswork: The Childhood Vaccine Schedule is Very Intentional

Public health expert and science communicator Dr Jess Steier and colleagues have recently published an article illustrating how the US recommended vaccine schedule is built on clinical trial data and ongoing safety monitoring. 

The article covers why vaccines are given at different timepoints, who determines the schedule, how new vaccines are added and how vaccines are continually monitored.
