Overview

• In an all-caps Truth Social post Friday, the president told pregnant women to avoid Tylenol unless “absolutely necessary” and told parents not to give it to young children.
• He also advised breaking up the MMR vaccine, delaying hepatitis B until age 12, and spacing shots across five visits, positions contradicted by longstanding immunization guidance.
• The FDA told clinicians that a causal relationship between acetaminophen and autism has not been established, noting it is the only over-the-counter fever reducer approved in pregnancy and that untreated high fevers carry risks.
• Leading obstetric and pediatric experts recommend judicious, shortest-duration dosing when needed because alternatives such as NSAIDs and aspirin carry known pregnancy harms.
• Physicians report immediate patient anxiety and altered care decisions, while Kenvue rejects a causal link and scrutiny grows over a cited researcher’s paid litigation work as large studies, including a 2024 Swedish sibling analysis, find no association.
