ACOG Releases 2026 Maternal Immunization Schedule

Washington, D.C.-Today, the American College of Obstetricians & Gynecologists (ACOG) released its 2026 maternal immunization schedule. The new schedule is endorsed by 13 medical societies and health organizations and marks the first time ACOG has formally released an immunization schedule that differs from federal vaccine recommendations. ACOG's new schedule will be an easily accessible resource for clinicians, public health agencies, and patients across the United States.

"Changing national recommendations coupled with rampant vaccine misinformation are resulting in confusion for both patients and health care professionals," said ACOG President Camille A. Clare, MD, MPH, CPE, FACOG. "It is incredibly important for the public to have access to reliable, evidence-based information on maternal immunizations from a trusted source. ACOG is proud to be that source."

The guidance was developed by ACOG's Immunization, Infectious Disease, and Public Health Preparedness Expert Work Group and reflects ACOG's continued commitment to developing vaccine guidance based on peer-reviewed scientific data and evidence-based medicine.

Clinicians are on the front lines of vaccine-related preventive care-assessing their patients' vaccination status, evaluating risk factors for vaccine-preventable diseases, and recommending the needed vaccines.

"Immunizations are an essential part of prepregnancy, prenatal, and postpartum care," said ACOG Chief of Clinical Practice Christopher Zahn, MD, FACOG. "ACOG's maternal immunization schedule is a tool that ob-gyns can use to start a dialogue with their patients about the importance of protecting themselves and their infants from vaccine-preventable diseases that can lead to poor health outcomes. As ob-gyns, we have the power to combat vaccine misinformation on our own platforms, help our patients make educated decisions, and increase confidence in vaccination overall."

The American Academy of Pediatrics, the American Academy of Family Physicians, the National Association of Nurse Practitioners in Women's Health, and the American College of Nurse-Midwives are among the 13 organizations that have endorsed ACOG's 2026 maternal immunization guidance.

American Academy of Family Physicians Chief Medical Officer Margot Savoy, MD, MPH, FAAFP
"Maternal immunization is one of the most effective ways we can protect both pregnant patients and babies during some of the most vulnerable stages of life," said Dr. Savoy. "Vaccines recommended during pregnancy help safeguard pregnant patients from serious illness while also providing critical early protection to newborns before they are old enough to be vaccinated themselves. Family physicians care for patients across generations, which puts us in a unique position to counsel families, build trust, and ensure that pregnant patients have access to evidence-based preventive care. Supporting maternal immunization means healthier pregnancies, healthier infants, and stronger communities."

American Academy of Pediatrics President Andrew Racine, MD, PhD, FAAP
"Babies are among the most vulnerable to vaccine-preventable diseases," said Dr. Racine. "Their immune systems are still developing, and in those first months of life, they rely on us-the adults around them-to help keep them safe. Maternal vaccines are one of the most effective ways to protect not only the mother but her newborn as well."

National Association of Nurse Practitioners in Women's Health President Jessica Wells, PhD, RN, WHNP-BC, FAAN
"As the professional community for women's health nurse practitioners and other nurse practitioners providing women's and gender-related health care services nationwide, the National Association of Nurse Practitioners in Women's Health sets a standard of excellence by generating, translating, and promoting evidence-based clinical guidance for various topics, including maternal health care," said Dr. Wells. "The National Association of Nurse Practitioners in Women's Health is honored to collaborate with ACOG and endorse their updated maternal immunization schedule, which integrates the most updated evidence with important patient-centered considerations to support clinicians in providing strong recommendations for immunizations in pregnancy and postpartum as a fundamental intervention."

American College of Nurse-Midwives CEO Michelle Monroe, DNP, APRN, CNM, FACNM, FAAN
"Midwives have long understood that the health of a community begins before birth, and the midwifery model centers the whole health and well-being of the pregnant person and their family as the foundation for lifelong health," said Monroe. "By endorsing the ACOG maternal immunization guidelines, the American College of Nurse-Midwives affirms that immunization during pregnancy is a safe, effective, and essential tool to improve birth outcomes; protect newborns from severe illness and hospitalization; and strengthen the health of entire communities through early, shared protection."
