The American College of Obstetricians and Gynecologists (ACOG) has introduced its first official maternal immunization schedule, marking an important development in pregnancy healthcare across the United States. The new guidance aims to provide clear, evidence-based recommendations for vaccinations during pregnancy and help healthcare professionals address growing confusion surrounding maternal immunization.
The 2026 Maternal Immunization Schedule was created to offer consistent recommendations for pregnant patients and clinicians. According to ACOG, the schedule is designed to improve maternal and infant health outcomes by encouraging the use of vaccines that help protect both mothers and newborns from serious infectious diseases.
ACOG stated that the decision to publish a dedicated vaccination schedule was driven by its commitment to evidence-based medicine and the need for reliable healthcare guidance. In recent years, conflicting public health messages and vaccine misinformation have contributed to uncertainty among both patients and healthcare providers.
One source of confusion emerged after public statements regarding COVID-19 vaccination recommendations for pregnant women. While discussions around vaccine guidance have varied, both the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Health and Human Services (HHS) currently continue to recommend COVID-19 vaccination during pregnancy.
Healthcare experts believe that providing a clear and unified immunization schedule can help improve confidence in maternal healthcare decisions and ensure that pregnant individuals receive accurate information from trusted medical organizations.
The newly released ACOG schedule highlights several vaccines considered important for protecting pregnant patients and their infants.
ACOG recommends that pregnant patients receive the influenza vaccine during pregnancy. While the vaccine can be administered at any stage of pregnancy, it is generally most beneficial during the fall influenza season when virus transmission is highest.
Seasonal influenza can lead to serious complications during pregnancy, making vaccination an important preventive measure.
The organization also recommends COVID-19 vaccination during pregnancy. According to the schedule, pregnant individuals may receive the vaccine at any point during pregnancy, although earlier administration may provide protection throughout a greater portion of the pregnancy.
Medical experts continue to emphasize the importance of COVID-19 protection for individuals at increased risk of complications from infection.
The tetanus, diphtheria, and pertussis (Tdap) vaccine remains a key recommendation during pregnancy. ACOG advises administration between 27 and 36 weeks of gestation.
Receiving the vaccine during this timeframe helps transfer protective antibodies to the developing baby, reducing the risk of pertussis, commonly known as whooping cough, during early infancy.
The respiratory syncytial virus (RSV) vaccine is another recommendation included in the new schedule. ACOG advises vaccination between 32 and 36 weeks of pregnancy during the RSV season, which generally runs from September through January in most regions of the United States.
RSV can cause serious respiratory illness in infants, and maternal vaccination can help provide newborns with early protection.
Beyond routine maternal vaccines, ACOG also outlines recommendations for other immunizations based on individual health risks and medical history.
These vaccines may include:
Healthcare providers are encouraged to evaluate each patient's risk factors to determine whether these vaccines are appropriate during pregnancy.
The guidance emphasizes personalized care and recognizes that vaccination needs may vary depending on medical conditions, lifestyle factors, occupational exposure, and travel history.
Some vaccines are not routinely administered during pregnancy and are instead recommended before conception or after childbirth.
Examples include:
These vaccines are important components of reproductive healthcare planning and can help protect both mothers and future pregnancies.
Healthcare professionals often review vaccination status during preconception counseling visits and postpartum care appointments to ensure patients remain protected against preventable diseases.
The maternal immunization schedule has received support from numerous healthcare organizations. ACOG reported that 13 additional medical and health groups have endorsed the recommendations.
Among the supporting organizations are:
The broad support from medical societies reflects a shared commitment to improving maternal and infant health through preventive care and vaccination.
By presenting consistent recommendations across multiple healthcare organizations, experts hope to reduce uncertainty and strengthen public trust in vaccine guidance.
Healthcare leaders have expressed concern about the increasing spread of vaccine misinformation through social media platforms and online sources. According to experts, misinformation has contributed to rising vaccine hesitancy in many communities.
ACOG leaders believe that a dedicated maternal vaccine schedule can serve as a reliable resource for both clinicians and patients seeking trustworthy health information.
Dr. Camille Clare, president of ACOG, noted that changing national recommendations and widespread misinformation have created confusion among healthcare professionals and the public. The organization hopes that its evidence-based guidance will help patients make informed decisions regarding maternal immunization.
Similarly, Dr. Christopher Zahn, ACOG's chief of clinical practice, emphasized that vaccines remain an essential component of prepregnancy, prenatal, and postpartum healthcare. He described the schedule as a practical tool that can facilitate productive conversations between patients and healthcare providers.
Vaccination during pregnancy serves two important purposes. First, it helps protect pregnant individuals from potentially serious infectious diseases. Second, it can provide passive immunity to newborns through the transfer of protective antibodies.
Newborns are particularly vulnerable to infections because their immune systems are still developing. Maternal immunization can help bridge this period of vulnerability until infants become eligible for their own vaccinations.
Public health experts continue to view maternal vaccination as one of the most effective strategies for reducing preventable illness in both mothers and infants.
The introduction of ACOG's first official maternal immunization schedule represents a significant milestone in women's healthcare. By offering clear recommendations based on scientific evidence, the organization aims to support informed decision-making and improve health outcomes for families.
As vaccine guidance continues to evolve, healthcare professionals encourage patients to discuss any questions or concerns with their obstetricians, midwives, or other qualified healthcare providers. Personalized medical advice remains essential when making healthcare decisions during pregnancy.
