World Immunisation Week - 24th–30th April

World Immunization Week (24 to 30 April) is a global reminder of one of the most powerful health breakthroughs we have: vaccines. Immunisation helps protect people of all ages from serious, preventable diseases, and it supports healthier communities by reducing illness, hospitalisation, and long term complications.

In 2025, the theme is Immunization for All is Humanly Possible. It highlights a simple truth: reaching more people with life saving vaccines is achievable through human effort, practical planning, and fair access to services.

World Immunization Week is not only about individual protection. It is also about protecting the people around us, including babies too young to be fully vaccinated, older adults, and people with weaker immune systems. Higher vaccination coverage helps reduce outbreaks and keeps essential spaces like schools, workplaces, and community services functioning more safely.

What you can do during World Immunization Week

• Check your immunisations and see if you are due for any boosters or catch up doses.
• Encourage family members to do the same, especially children, older relatives, and anyone at higher health risk.
• Use trusted information when sharing health advice online. When in doubt, refer people to official guidance.
• Learn about Hepatitis B protection and why vaccination can matter for lifelong liver health, which is a focus raised by Australian health advocates during International Immunisation Week.

World Immunization Week is a chance to celebrate progress while focusing on what still needs to improve: more coverage, fewer barriers, and better access for every community. If immunisation reaches everyone, it does not just save lives, it strengthens the everyday systems we all rely on.
