FOR EVERY GENERATION, VACCINES WORK World Immunisation Week 2026 | 24–30 April

There’s something quietly remarkable about vaccines. They don’t make headlines the way new drugs or medical breakthroughs do. They’re just… there. A jab at the GP. A card your mum kept in a drawer. A ritual so ordinary that most of us never think twice about what it’s actually preventing.

But this 24 to 30 April — World Immunisation Week — is a good moment to stop and think about it.

This year’s theme is “For every generation, vaccines work”, and the numbers behind that phrase are genuinely staggering. Over the past 50 years, vaccines have saved more than 150 million lives — not through luck or accident, but because generations of families made the choice to protect themselves and those around them. Measles, diphtheria, polio, whooping cough — diseases that used to devastate communities — are now largely preventable. Newer vaccines against HPV, malaria, RSV, Ebola, and mpox are continuing that work, helping people at every stage of life live longer and healthier.

That matters here in Australia just as much as anywhere else. Our National Immunisation Programme is one of the best in the world, but it only works when enough of us participate. Herd immunity isn’t just a textbook concept — it’s the reason that babies too young to be fully vaccinated, immunocompromised people, and elderly Australians are kept safe by the choices their neighbours make. When vaccination rates slip, diseases come back. We’ve seen it happen.

Still, around 20 million children worldwide missed at least one vaccine dose in 2024. The global picture is a reminder that the work isn’t done — and that confidence in vaccines needs to be actively maintained, not assumed.

WHO is calling for renewed global efforts to ensure everyone, everywhere has access to life-saving vaccines, delivered through trusted health services that meet people’s needs. Building that trust starts with accurate information, open conversations, and communities that feel supported rather than lectured.

So what can you do this week? Check that you and your family are up to date. If you’re unsure about the schedule, your GP or local pharmacist can help. Talk to friends or family who might have questions about vaccines — not to argue, but to share what you know. And if you’re on social media, the campaign hashtags #VaccinesWork and #WorldImmunizationWeek are worth adding to the conversation.

Vaccines aren’t new. They aren’t experimental. They’re one of the most tested, most trusted tools in public health history — and they’ve been quietly protecting your family for generations. That’s worth a moment of recognition.
