WASHINGTON — U.S. President Donald Trump has signed a executive order calling for a reduction in recommended childhood vaccinations and urging healthcare providers to split the combination measles, mumps, and rubella (MMR) shot into three separate doses administered over multiple doctor visits.
Speaking at the signing, Trump cast doubt on current immunization schedules, reviving long-debunked claims connecting pediatric shots to neurodevelopmental conditions.
“Decades ago, children received only a small fraction of the vaccines required today,” Trump said. “In those times, people were much healthier and of course the high rates of autism now observed did not exist.”
Overhauling the Federal Childhood Immunization Schedule
The new executive order dramatically alters federal guidance, dropping the number of universally recommended childhood disease immunizations from 18—the standard established by the American Academy of Pediatrics (AAP) and Centers for Disease Control and Prevention (CDC)—down to 11.
Because school-entry vaccination mandates are determined at the state level, the White House directive functions as federal guidance rather than a binding national mandate.
Vaccines Retained for All Children Under the Executive Order:
• Measles, Mumps, & Rubella (MMR)
• Diphtheria, Tetanus, & Pertussis (DTaP)
• Polio & Varicella (Chickenpox)
• Haemophilus influenzae type B (Hib)
• Pneumococcal disease & Human Papillomavirus (HPV)
Trump argued that spacing out immunizations across more frequent appointments is safer for young children. “It’s not only that you’re doing fewer vaccines, or jabs, as they say, but you’re doing them in a series of visits to the doctor,” he stated, comparing giving combination vaccines like the MMR to “pouring a bottle of soda into a child’s body.”
When questioned by reporters for scientific evidence supporting his assertion that combination vaccines could be “quite lethal,” Trump responded: “What I’ve heard is that there are some people that say it is that way.”
Medical Community and Lawmakers Express Severe Concerns
Medical experts, public health agencies, and lawmakers swiftly condemned the directive, warning that delaying immunizations and adding extra clinical visits increases the risk of childhood disease outbreaks.
-
Increased Health Risks: AAP President Dr. Andrew Racine labeled the order “dangerous” and unsupported by “gold-standard science,” warning that “delaying or skipping shots is risky, especially as measles continues to spread.”
-
Logistical Burden on Parents: Dr. William Schaffner of the Vanderbilt University School of Medicine noted that requiring multiple visits makes tracking appointments far harder for working families, increasing costs without providing any medical benefit.
-
Bipartisan Political Pushback: Republican Senator Bill Cassidy, a physician whose vote was decisive in confirming Health Secretary Robert F. Kennedy Jr., publicly criticized the decision on X: “The President does not have the expertise to make these changes. Vaccines are overwhelmingly safe. Vaccines are effective. Vaccines DO NOT cause autism.”
CDC and AAP Guidelines on MMR Safety and Aluminum Content
The CDC and AAP maintain that there is no published scientific evidence showing any benefit to separating the MMR shot into individual injections.
Furthermore, extensive global research—including a landmark 2019 Danish study of over 650,000 children—has repeatedly confirmed no link between the MMR vaccine and autism.
-
MMR Dosage & Safety: The CDC notes that a standard MMR dose is 0.5 mL and that serious adverse reactions are extremely rare. The agency stresses that receiving the combined shot carries far lower health risks than contracting measles, mumps, or rubella.
-
Aluminum Salts in Vaccines: Responding to the executive order’s directive to seek alternatives to aluminum adjuvants, the AAP emphasized that tiny amounts of naturally occurring aluminum salts have been safely used for decades to boost immune response, allowing for smaller dosages and fewer overall shots.
