A Wake-Up Call for Australia's Child Vaccination Rates: Are We Sliding Backwards?
Australia has long been a shining example of successful child vaccination, with rates among the highest in the world. However, a recent and rapid decline in vaccination coverage is a cause for concern, and we must act now to prevent a potential public health crisis.
Before the COVID-19 pandemic, Australia proudly achieved a national target of 95% of one-year-olds fully vaccinated. This was a remarkable feat, protecting children from serious illnesses like measles, mumps, and whooping cough. These diseases can cause immense suffering, leading to hospitalization, life-threatening complications, and long-term health issues.
But here's where it gets controversial: post-pandemic, Australia's vaccine success story has taken a turn for the worse. The percentage of fully vaccinated one-year-olds has been steadily declining, with some areas now barely reaching 80%.
The risks are very real. Whooping cough cases are at their highest in 35 years, and measles exposure sites have been identified in Sydney and regional New South Wales, including hospitals and schools. We cannot afford to become complacent and ignore these warning signs.
And this is the part most people miss: high vaccination coverage is crucial for achieving herd immunity. When 95% of children are vaccinated, it creates a protective barrier, making it difficult for highly contagious diseases to spread. This safeguards not only the vaccinated but also those who cannot be vaccinated due to age or weakened immune systems.
However, Australia's vaccination rates are sliding backwards. Grattan Institute analysis reveals an unprecedented decline over the past five years. In the year to September 2025, only 92% of one-year-olds were fully vaccinated, compared to 95% in 2020. Many regions are now well below national targets, with just 18% of areas meeting the one-year-old vaccination goal today, down from 56% five years ago.
The declines have been most pronounced in areas where children were already more vulnerable. For instance, in the 10% of areas with the highest vaccination rates for one-year-olds, uptake only slid by 1.3 percentage points since 2020. But in areas with lower vaccination rates, the fall was more than four times greater, dropping from an average of 90% in 2020 to 84% in 2025.
So, what's causing this decline? It's a complex issue, with a mix of psychological and practical barriers. Misinformation and the intense debate surrounding COVID-19 vaccines have likely eroded trust in childhood vaccination. Among parents with unvaccinated children, almost half don't believe vaccines are safe. Additionally, practical barriers, such as difficulty securing appointments, also play a role.
Australia's federal and state governments recognize the problem and have developed a new national vaccination strategy. This strategy aims to build trust in vaccines, strengthen the immunisation workforce, utilize data to target efforts, and increase accountability. However, the true test will be the upcoming federal and state government budgets. New investments must be made to turn this strategy into decisive action.
The investments should address a range of issues, including public advertising, combating misinformation, modernizing data systems, and delivering vaccinations in more accessible locations like workplaces and community centers. Crucially, tougher targets and funding for local efforts tailored to specific needs are essential to prevent certain communities from falling further behind.
Australia has proven its ability to achieve ambitious vaccination targets in the past. Getting back to pre-pandemic levels will be a challenging task, but it is one that must be undertaken to protect our children's health. So, let's not shy away from this crucial conversation.
