WHO chief says Trump vaccine push goes against ‘decades of evidence’

The World Health Organization (WHO) Director-General, Tedros Adhanom Ghebreyesus, has criticized US President Donald Trump's initiative to change childhood vaccination policies, stating it disregards "decades of evidence." This comes after Trump signed an order to re-evaluate school vaccine mandates and reconsider separating the MMR vaccine into three individual doses. The article notes that US Health Secretary Robert F. Kennedy Jr. has promoted a discredited link between the MMR vaccine and autism. Tedros emphasized that scientific evidence unequivocally shows vaccines, including MMR, are safe and do not cause autism. He asserted that vaccination policy should be based on scientific review, not political influence, and warned that delaying or unnecessarily separating vaccine doses can leave children vulnerable.

The World Health Organization (WHO) has warned that President Donald Trump's recent actions regarding US child vaccination policy contradict established scientific evidence. On Monday, Trump signed an order to re-evaluate school vaccine mandates and reiterated calls to separate the measles, mumps, and rubella (MMR) vaccine into individual shots. The WHO director general, Tedros Adhanom Ghebreyesus, stated that the science is clear: vaccines, including MMR, are safe and do not cause autism. He emphasized that vaccination policy should be based on scientific review, not political influence, and expressed concern that the US policy changes are not aligned with decades of evidence regarding child vulnerability to disease.

President Donald Trump signed an executive order aimed at scaling back the childhood immunization schedule and spacing out vaccine doses. This move aligns with Trump's long-held, though scientifically discredited, belief that vaccines should be administered over a longer period. While the order may appeal to some "Make America Healthy Again" voters seeking more flexibility, it has also provided Democrats with an attack line for the upcoming midterm elections. Democrats plan to use the order to highlight their commitment to science-based healthcare. Public health experts warn that spacing out vaccinations could increase the risk of infection before a child receives subsequent doses.

President Donald Trump signed an executive order on August 10, 2026, urging states to revise childhood vaccine recommendations, including separating the MMR vaccine. During the signing, Trump and Health and Human Services Secretary Robert F. Kennedy Jr. made several false claims regarding vaccine safety, the number of injections, and a link to autism. Public health experts expressed concern, stating that spacing out vaccines could increase the risk of preventable diseases and that existing vaccines are safe and effective. Studies have consistently shown no link between vaccines and autism. The article debunks claims about the number of vaccine injections and the volume administered, emphasizing that current vaccine schedules are rigorously studied and proven to protect children.

President Donald Trump signed an executive order on Monday to revamp childhood vaccine recommendations. The order promotes the idea of spacing out childhood immunizations into separate medical visits, including separating the MMR vaccine into three single-disease shots. It also directs the nation's health department to improve vaccine research and develop a plan to offer separate measles, mumps, and rubella vaccines, which are not currently available in the U.S. This action aligns with Trump's long-held theory regarding vaccine scheduling.

President Donald Trump has signed an order proposing fewer childhood vaccines and the separation of the mumps, measles, and rubella (MMR) vaccine into three individual shots. Trump stated that in the past, when children received fewer vaccines, they were healthier and autism rates were not as high. The article notes that the Trump administration has promoted a discredited link between vaccines and autism, and that multiple studies have found no such connection with the MMR vaccine.
