Overview
- On Wednesday, June 10, 2026, the American College of Obstetricians & Gynecologists published its first Maternal Immunization Schedule that formally diverges from current CDC advice.
- ACOG recommends four routine vaccines during pregnancy — influenza, COVID-19, RSV and Tdap — with specific timing guidance for each to protect mothers and newborns.
- Thirteen other professional societies endorsed ACOG’s schedule and some groups, including the American Academy of Pediatrics, have issued their own guidance that also differs from the CDC.
- ACOG says it acted because changing federal recommendations and widespread misinformation have confused clinicians and patients and reduced confidence in maternal vaccines.
- The split matters for care and policy because the CDC currently recommends only Tdap and RSV during pregnancy, legal challenges to the federal changes continue, and clinicians may face conflicting guidance when advising patients.
