MAHA（“让美国再次健康”）运动已明显降温；当时曾在特朗普第二任期后仅24天确认罗伯特·F·肯尼迪 Jr. 为卫生部长，并由CDC推出“疫苗与自闭症”研究且更换顶级疫苗监管者时，进展一度非常迅猛。如今白宫和国会都显得趋于倦怠，许多最初寄望MAHA带来选举红利的共和党人，正担心其正变成一把棱镜式政治分裂议题。
MAHA衰退最明显的迹象之一是主要公共卫生职位出现空缺：CDC既无现任主任也无代理主任，而斯坦福健康经济学家Jay Bhattacharya在兼管国立卫生研究院（NIH）的同时还监管CDC，需在相距约640英里的岗位之间管理约27,000名员工。与此同时，Casey Means的外科医生（Surgeon General）提名听证会已过去一个月以上仍未安排参议院表决，她在听证中未明确推荐疫苗，且官方提及的今年麻疹病例超过1,500例增强了对这一空缺的担忧。
这些延误被认为源于确认程序僵局，也有共和党人解读为故意回避高风险政治对抗，白宫虽坚持支持MAHA并称其仍有进展，但压力正在扩大。最新的Economist/YouGov民调显示，接近四分之三美国人认为疫苗“有些安全”或“非常安全”，特朗普阵营首选民调员Fabrizio Ward警告疫苗要求上的怀疑论在政治上危险，而三月联邦法院已暂停包括减少儿童疫苗接种剂次数等新疫苗政策后，政府虽表示将上诉。
The MAHA movement has clearly cooled: it had surged when Robert F. Kennedy Jr. was confirmed as health secretary just 24 days into Trump’s second term, and when the CDC announced a vaccine-autism study while top vaccine regulators were pushed out. The White House and Congress now look fatigued, and many Republicans who once expected electoral gains from MAHA now fear the issue has become a political wedge.
One clear signal is the vacancy at top public-health posts: the CDC still has no director or acting director, while Stanford health economist Jay Bhattacharya simultaneously runs the NIH and oversees the CDC, managing about 27,000 employees across facilities about 640 miles apart. More than a month has passed since Casey Means’ surgeon-general confirmation hearing, yet no Senate vote has been scheduled; she avoided directly endorsing vaccines in the hearing and officials cite more than 1,500 measles cases in the U.S. this year.
The delays are now attributed to confirmation deadlock, with some Republicans reading it as a deliberate way to avoid bruising fights, even as the administration claims MAHA is still advancing. Public and legal pressure is rising: a recent Economist/YouGov poll found nearly three-quarters of Americans say vaccines are somewhat or very safe, preferred pollster Fabrizio Ward warns vaccine-skeptic messaging is politically risky, and a March federal court pause on policies including fewer child vaccine doses has prompted an administration appeal promise.
