The American College of Obstetricians and Gynecologists released its updated maternal immunization guidelines for the 2026-2027 respiratory virus season on September 9, 2026. The new recommendations address vaccination schedules for COVID-19, influenza, and respiratory syncytial virus (RSV) to help improve uptake among pregnant patients.
Why it matters
Inconsistent guidance and vaccine hesitancy have lowered immunization rates across the United States, leaving pregnant patients and infants at higher risk for severe illness. These guidelines aim to protect families by clarifying vaccination windows and the clinical benefits of preventing respiratory infections.
Data shows maternal COVID-19 vaccination correlates with a 58% reduced risk for urgent care visits, while unvaccinated pregnant patients face a 4-fold higher risk for hospitalization. RSV vaccination coverage was 41.6% in the 2025-2026 season, with the current recommended window set from September 1 to March 1.
The players
American College of Obstetricians and Gynecologists
A professional membership organization that establishes clinical practice guidelines for obstetric and gynecologic care.
Texas Children's Hospital
A major pediatric healthcare institution involved in the clinical research and development of these maternal health recommendations.
Boston Medical Center
A research-focused health system that contributes to clinical standards for maternal and infant immunizations.
The details
The new guidelines encourage clinicians to use presumptive communication—the practice of confidently recommending a vaccine as the standard of care—to address patient hesitancy. Pregnant patients can access these immunizations at pharmacies, which are recognized as primary hubs for vaccine administration. For RSV, the vaccine is recommended to protect infants, as trial data demonstrates that immunization during pregnancy can significantly lower the risk of severe lower respiratory tract infections in the first 90 days of life.
Timeline
The American College of Obstetricians and Gynecologists held an informational webinar on September 9, 2026.
The respiratory syncytial virus vaccination window is officially set from September 1 to March 1.
The Home Front
This guidance marks a significant shift in maternal healthcare by establishing the first independent immunization schedule from the American College of Obstetricians and Gynecologists. The development standardizes clinical practice to combat recent trends of inconsistent vaccine uptake.
Review your vaccination records and speak with your healthcare provider or local pharmacist about which immunizations are appropriate for your current pregnancy stage. Ensure your questions are addressed ahead of the seasonal peak windows for influenza and respiratory syncytial virus.
The takeaway
Clear communication and proactive scheduling are the best tools for protecting the health of parents and infants this season. Use your next prenatal appointment to map out a vaccination plan that aligns with the current September 1 to March 1 window for RSV prevention.
