Australian medical experts are sounding a critical alarm regarding a recent shift in child vaccination advice originating from the United States. They contend that this change is not rooted in scientific evidence and poses a significant threat to decades of progress in public health.
The concern stems from an unprecedented executive order signed by US President Donald Trump. This order advocates for a reduction in the number of diseases American children are vaccinated against, implicitly suggesting a link between vaccines and autism, despite a complete lack of supporting evidence. Under this new guidance, the official number of recommended immunizations for children would decrease to 11, a considerable drop from the 18 recommended at the end of 2024. Of these 11, only six would be universally recommended, with the remaining five, including the hepatitis B vaccine, reserved solely for high-risk children.
In stark contrast, Australia currently recommends 15 childhood vaccinations. Health experts in Australia firmly assert that all of these vaccinations are fundamental to safeguarding children’s health.
Professor Julie Leask, a distinguished social scientist at the University of Sydney and an authority on social behaviors surrounding vaccination, views Trump’s decision, alongside his endorsement of US health secretary and vaccine skeptic Robert F. Kennedy Jr., as a direct threat to vaccine uptake within Australia. Leask emphasizes that “Anything Trump says filters through to Australia. Australian parents and caregivers hear it, and it does affect a minority of people and makes them wonder about vaccines and their safety.”
Having studied vaccination rates for decades, Leask, a trained midwife, reports that health professionals are already witnessing the ramifications of Trump’s rhetoric in Australia. Nurses, for instance, are increasingly encountering parents expressing concerns about vaccination. Leask notes, “Some of my colleagues are worried that we’re kind of going back to the future,” highlighting a regression in public confidence.
Further evidence of this concerning trend emerged from a national survey of Australian parents released in February, which indicated a decline in parental acceptance of routine childhood vaccinations compared to the previous year. Data from the Australian Immunisation Register reveals that full childhood vaccination rates peaked between 2020 and 2021. Currently, the coverage rate for all five-year-old children stands at 92.6%, falling short of the desired 95% target.
Lucy Clynes, the chief executive of Hepatitis Australia, expresses profound apprehension regarding the impact of Trump’s policies on vaccine confidence in Australia. Her organization analyzed search term trends over the past year and discovered a clear correlation: whenever the US government issues statements that undermine vaccine efficacy or safety, Australians engage in increased online searches to validate such claims.
Clynes points to a tangible consequence: “There has been a 3% drop in the number of one-year-olds who are fully immunised for hepatitis B in Australia, a downward trend since about 2020.” She explains that when Australians encounter statements from the US government, they often turn to search engines like Google or Instagram, where the information they encounter can be inaccurate and alarming. “When people start doing their own research on vaccines, it means they haven’t immediately trusted what their healthcare provider has told them… And that worries us,” Clynes elaborates.
Hepatitis B is a viral infection that affects the liver and is the most prevalent blood-borne virus in Australia. A significant number of infected individuals develop a chronic, lifelong infection which, over time, can lead to severe liver damage, including liver cancer and cirrhosis. There is currently no cure for chronic hepatitis B, and over 230,000 Australians are living with this condition.
Fortunately, vaccination provides a high degree of protection against hepatitis B. In Australia, infants are recommended to receive a course of four vaccines to prevent the disease, including one at birth. This initial dose is crucial as it can prevent infection even if the mother is a carrier.
Professor Ben Cowie, director of the WHO Collaborating Centre for Viral Hepatitis, lauds the extraordinary public health benefits of hepatitis B vaccination efforts in Australia, crediting them with saving thousands of lives. He states, “We know that [vaccination programs are] having a profound impact, particularly in high prevalence countries, many of which are in our region.”
However, Cowie acknowledges the concerning rise in vaccine hesitancy and the downward trend in childhood vaccination rates. He emphasizes that despite the hepatitis B vaccine having been administered to billions worldwide and proven to be remarkably safe and effective, this growing apprehension cannot be overlooked.
In response to these concerns, the Australasian Society for Infectious Diseases (ASID) has issued a statement reassuring parents about the safety of the measles, mumps, and rubella (MMR) vaccine. They assert that there is no scientific basis for altering the recommended schedule for children in Australia and New Zealand. Trump’s executive order, if implemented, would see the single MMR injection split into three separate appointments. ASID substantiated their statement by attaching ten published studies, all unequivocally demonstrating the scientific safety and effectiveness of the MMR vaccine as currently administered.
The ASID urges parents with questions about vaccination to consult their general practitioner, pediatrician, immunization nurse, or other trusted healthcare professionals. They reiterate a crucial message: “The science has not changed: MMR vaccination is a safe and effective way to protect children from measles, mumps and rubella.”
