New Vaccine Schedule Released By American College of Obstetricians & Gynecologists

The American College of Obstetricians & Gynecologists (ACOG) introduced its first formal maternal immunization schedule on June 11, 2026, addressing confusion caused by conflicting public health guidance. The move follows a 2025 tweet by HHS Secretary Robert F. Kennedy Jr., which suggested the COVID-19 vaccine was no longer recommended for pregnant women—a claim contradicted by the CDC and HHS, which still endorse vaccination. ACOG’s 2026 schedule prioritizes vaccines offering the most protection during pregnancy and early infancy. Pregnant patients are advised to receive the flu vaccine anytime (ideally in fall), the COVID-19 vaccine as early in pregnancy as possible, the Tdap vaccine between 27 and 36 weeks, and the RSV vaccine between 32 and 36 weeks during flu season. Risk-based recommendations also cover hepatitis A/B, meningococcal, and pneumococcal vaccines, while others like MMR, HPV, and chickenpox are advised before or after pregnancy. The guidelines follow ACOG’s withdrawal from a CDC vaccine advisory committee earlier this year and are supported by 13 medical groups, including the American Academy of Pediatrics and Family Physicians. Dr. Christopher Zahn, ACOG’s chief of clinical practice, emphasized that immunizations are critical in prepregnancy, prenatal, and postpartum care, helping clinicians discuss vaccine benefits with patients. ACOG President Dr. Camille Clare noted that misinformation and shifting recommendations have created confusion for patients and healthcare providers. The schedule aims to provide a trusted, evidence-based resource to counter online disinformation and rebuild public trust in maternal vaccinations. A patient-friendly version of the schedule is available online for reference.
