Maternal Immunization

  • Practice Advisory PA
  • October 2022

This Practice Advisory was developed by the American College of Obstetricians and Gynecologists in collaboration with Kevin A. Ault, MD, FACOG, and Laura E. Riley, MD, FACOG.


This Practice Advisory serves as an update to the American College of Obstetricians and Gynecologists (ACOG) Committee Opinion No. 741, Maternal Immunization, originally published in 2018 1 .

Background

Immunization is an essential part of care for adults, including pregnant individuals. Since the publication of Committee Opinion No. 741, Maternal Immunization, the Centers for Disease Control and Prevention (CDC) has continued to release annual immunization schedules for children, adolescents, and adults. The CDC’s 2022 adult immunization schedule 2 includes several updates to immunization recommendations impacting pregnant individuals.

These updates include a universal recommendation for hepatitis B vaccination for all unvaccinated adults, including pregnant adults; changes to pneumococcal vaccine recommendations to reflect newly available vaccines; and added recommendations for COVID-19 vaccination.

Updated ACOG Recommendation

Based on the CDC’s 2022 adult immunization schedule and its supporting evidence of benefit, ACOG recommends hepatitis B vaccination for all unvaccinated pregnant adults 3 . Additionally, ACOG recommends pneumococcal vaccination for pregnant individuals at increased risk of severe pneumococcal disease 4 .

ACOG recommends COVID-19 vaccination for all pregnant individuals who were not vaccinated prior to pregnancy. Pregnant and recently pregnant people up to 6 weeks postpartum should receive a bivalent mRNA COVID-19 vaccine booster dose following the completion of their last COVID-19 primary vaccine dose or monovalent booster. COVID-19 vaccines are recommended for postpartum and lactating individuals who were not vaccinated prior to or during pregnancy 5 Table 1 .

A Practice Advisory is a brief, focused statement issued to communicate a change in ACOG guidance or information on an emergent clinical issue (eg, clinical study, scientific report, draft regulation). A Practice Advisory constitutes ACOG clinical guidance and is issued only on-line for Fellows but may also be used by patients and the media. Practice Advisories are reviewed periodically for reaffirmation, revision, withdrawal or incorporation into other ACOG guidelines. This information is designed as an educational resource to aid clinicians in providing obstetric and gynecologic care, and use of this information is voluntary. This information should not be considered as inclusive of all proper treatments or methods of care or as a statement of the standard of care. It is not intended to substitute for the independent professional judgment of the treating clinician. Variations in practice may be warranted when, in the reasonable judgment of the treating clinician, such course of action is indicated by the condition of the patient, limitations of available resources, or advances in knowledge or technology. The American College of Obstetricians and Gynecologists reviews its publications regularly; however, its publications may not reflect the most recent evidence.
