Trump order pushes for overhaul of childhood vaccine schedule

WASHINGTON – US President Donald Trump signed an executive order on Aug 10 pushing for a rethink of school vaccine mandates and repeating calls for the measles, mumps, and rubella (MMR) vaccine to be separated into three individual shots.

Many medical experts cast the push as scientifically baseless and potentially damaging to public health.

Curbing vaccines has been a key priority for Health Secretary Robert F. Kennedy Jr, who founded an anti-vaccine nonprofit and has long promoted a disproven link between immunisation and autism.

The federal government does not have direct control over several areas covered by the order. States, for example, have the authority to require vaccinations for students to attend school.

On these points Trump’s move is more of a suggestion than an order.

“States and territories are advised to review” the Trump administration’s recommendations on “immunisation requirements for contexts such as school enrolment and attendance”, the order states.

In another section, it says the US Health and Human Services department will form a task force to offer the MMR shot as individual vaccines “by working with the private sector and other countries as appropriate, while guaranteeing continued availability of combination vaccines and those vaccines recommended for shared clinical decision-making”.

New York City’s health commissioner, Alister Martin, said the order was based “in politics and conspiracy theories”.

“Fortunately, vaccination recommendations are not set by the president, nor should they be,” Martin said in a statement.

“Cities and states can set their own recommendations and requirements, and many, including New York City, have moved away from the federal government’s recommendations as they’ve become politicised and unscientific.”

Years of clinical evidence support the safety of a combined MMR vaccine.

Public health experts have long advised that the combined shot offers children more protection faster, and also decreases the logistical hurdles for parents who may struggle to make multiple appointments.

Yet during the Oval Office signing, Trump made a series of incendiary and unsupported statements countering that advice.

In a call with reporters, Andrew Racine, president of the American Academy of Paediatrics (AAP), estimated it would take more than a decade to develop approved separated vaccines in the US.

“We’re advising that you continue to give children a vaccine that has decades of safety data,” added Aaron M. Milstone, a member of the AAP Committee on Infectious Diseases.

Worst measles outbreak in decades

Senator Bill Cassidy, a doctor whose deciding vote confirmed Kennedy’s controversial appointment as health chief, posted on social media platform X that the president’s initiative would only serve to “increase hesitancy and make children less safe”.

“This executive order is wrong. The President does not have the expertise to make these changes. Vaccines are overwhelmingly safe. Vaccines are effective. Vaccines DO NOT cause autism,” Cassidy said.

The Trump administration’s push to overhaul vaccine policy comes as its efforts to implement major changes were blocked by a federal court earlier in 2026, pending further court proceedings.

The judge’s stay preventing the overhaul sided with major medical organisations, which asserted that the Trump administration’s actions to push the changes through were unlawful.

The president’s latest order arrives just as children across the country are readying to return to school, and as the US suffers its worst measles outbreak in 35 years.

Trump’s health secretary Kennedy is accused of contributing significantly to the crisis by spreading anti-vaccine sentiment and fuelling fears of well-studied and proven immunisations.

Polling indicates that most Americans still support vaccination, and in recent months both Kennedy and Trump had backed off anti-vaccination rhetoric which could spell negative repercussions in November’s midterm vote.

But the efforts on Aug 10 show the issue remains a core component of their health policy agenda, as both men remain committed to the false notion that vaccines can cause autism.

Such a potential link has been debunked by years of research. AFP
