特朗普政府于2026年8月10日签署行政命令，将美国儿童推荐疫苗从18种减少至11种[1]。这项名为《为美国人提供金标准儿童疫苗建议》的政策建立了三个疫苗接种类别，分别为全体儿童推荐的11种疫苗、高风险人群的疫苗和需要医患共同决策的疫苗[1]。被删除的疫苗包括乙肝、轮状病毒、流感和呼吸道合胞病毒疫苗[1]。
该政策还建议将国际通用的三联MMR疫苗分离为单独注射[1]。这一调整被认为反映了特朗普政府长期声称疫苗导致自闭症的观点。对此，美国疾病控制与预防中心表示，MMR疫苗不对儿童自闭症增加负责[1]。美国儿科学会主席Andrew Racine批评这项政策"不基于金标准科学，没有新证据证明需改变儿童免疫指南"[1]。相比之下，世界卫生组织推荐12种疫苗接种，德国推荐14种儿童疫苗接种[1]。
President Donald Trump signed an executive order on August 10, 2026, reshaping America's childhood vaccination recommendations by cutting the list of advised immunizations from 18 to 11 vaccines [1]. The order, titled "Providing Americans with Gold Standard Recommendations for Childhood Vaccines," establishes three vaccination categories: 11 vaccines recommended for all children, vaccines for high-risk populations, and vaccines requiring shared decision-making between parents and physicians [1].
The policy removes four vaccines from the standard recommendation schedule: hepatitis B, rotavirus, influenza, and respiratory syncytial virus (RSV) [1]. Additionally, the order proposes separating the MMR triple vaccine—which protects against measles, mumps, and rubella—into three individual injections rather than the combined formulation [1]. The administration's approach reflects longstanding claims by Trump that vaccines cause autism, though the CDC has stated that "MMR vaccine is not responsible for an increase in autism in children" [1].
The medical community has expressed significant concerns about the directive. Andrew Racine, president of the American Academy of Pediatrics, stated that the policy is "not based on gold standard science" and lacks new evidence to justify changes to established childhood immunization guidelines [1]. Internationally, the World Health Organization recommends 12 vaccines for children, while Germany advises 14 [1].
