Trump takes aim at childhood vaccines - Vox

Theory Briefing

• Trump claimed on Monday that childhood vaccine doses are excessive, escalating his long-running amplification of vaccine-autism theories.
• The autism-vaccine claim originated largely from a 1998 study later retracted and its author stripped of his medical license.
• Repeated large-scale studies have found no link between vaccine schedules and autism, yet the belief persists widely among the public.
• A sitting president voicing these claims gives institutional weight to a fringe position, potentially influencing vaccination rates.
