President Donald Trump signed an executive order to overhaul federal childhood vaccine guidelines in the United States. The order reduces the number of recommended immunizations from 18 to 11 and mandates that the measles, mumps, and rubella (MMR) vaccine be administered as three separate shots rather than a combination injection. The policy also suggests spacing out immunizations across multiple medical visits and introduces risk-based criteria or shared decision-making for vaccines including COVID-19, influenza, hepatitis A and B, and rotavirus. The administration, including Health and Human Services Secretary Robert F. Kennedy Jr., has linked these changes to concerns regarding autism and aims to increase parental choice. The World Health Organization (WHO) has criticized the move, stating the changes lack support from available scientific data and should not be driven by political influence. The WHO emphasized that current evidence remains indisputable: vaccines, including the MMR vaccine, are safe and do not cause autism. Public health experts and medical professionals have warned that the new requirements could create logistical and financial burdens for families, strain the pediatric healthcare system, and leave children vulnerable to preventable ~~diseases during outbreaks.~~ diseases. Republican Senator Bill Cassidy, a physician, specifically criticized the order, arguing that separating doses would increase costs and logistical burdens. Pharmaceutical experts noted that the order would require drugmakers to revive discontinued individual vaccines and develop new manufacturing capacity. Following the order, the administration has moved to establish a dedicated task force within the Department of Health and Human Services to review federal ~~recommendations.

The Centers for Disease Control and Prevention (CDC) has begun focusing on comparative data from countries such as Denmark, the United Kingdom, Germany, and Japan to evaluate dose counts. While federal policy shifts, state-level vaccine mandates for school and daycare entry remain legally separate from federal advisory guidelines, which may limit the immediate impact at the local level.
