The American College of Obstetricians and Gynecologists (ACOG) released a new, independent immunization schedule for pregnant and breastfeeding individuals this week, diverging from current U.S. Centers for Disease Control and Prevention (CDC) guidelines. According to Dr. Christopher Zahn, ACOG’s chief of clinical practice, the move aims to provide evidence-based clarity amid shifting federal recommendations and rising vaccine misinformation. The new schedule, endorsed by 13 professional medical societies, maintains alignment with historical CDC protocols that existed prior to recent policy changes under the Trump administration and Health Secretary Robert F. Kennedy Jr.
Why is ACOG issuing its own vaccine schedule?
ACOG officially withdrew from the CDC’s Advisory Committee on Immunization Practices earlier this year, citing concerns over policy shifts that have since spurred legal challenges. By publishing its own schedule, the organization intends to bypass the confusion caused by conflicting federal messaging. Dr. Zahn stated that the goal is to communicate clear, data-backed guidance to patients who are increasingly bombarded by non-scientific claims on social media. This shift marks a significant moment where a major medical specialty group is reclaiming the authority to set clinical standards for its patient population independent of federal political shifts.
How do the new recommendations compare to federal guidelines?
The primary point of divergence centers on the COVID-19 vaccine. While the current U.S. Department of Health and Human Services, led by Robert F. Kennedy Jr., has publicly stated that COVID-19 vaccines are no longer recommended for healthy pregnant women, ACOG continues to advise that the shots be administered during any trimester. Other routine recommendations from ACOG include the flu vaccine, Tdap for pertussis protection, and the RSV vaccine. The following table highlights the core differences in clinical approach:
| Vaccine | ACOG Recommendation | Recent Federal Stance |
|---|---|---|
| COVID-19 | Recommended for all trimesters | Not recommended for healthy pregnant women |
| Flu | Routine (any trimester) | Routine |
How are healthcare providers addressing vaccine hesitancy?
Clinicians are reporting a surge in patients who arrive at appointments with misinformation gathered from online sources. Carol Hayes of the American College of Nurse Midwives noted that “vaccine hesitancy is huge” and directly linked to the difficulty patients face when trying to distinguish between peer-reviewed science and social media conjecture. Similarly, Sarah Vaillancourt of the National Association of Nurse Practitioners in Women’s Health stated that members of her organization are using the new ACOG guidelines as a primary tool to rebuild trust and provide patients with a definitive, scientifically vetted resource.
Frequently Asked Questions
Does the new ACOG schedule change when I should get my flu shot?
No. ACOG continues to recommend the flu vaccine during any trimester, noting that early fall is the optimal time for administration.

Do I need an RSV vaccine if I had one during a previous pregnancy?
According to ACOG, you do not need the RSV vaccine again if you received it during a prior pregnancy. Instead, the focus shifts to ensuring the newborn receives an antibody shot after birth.
Is the COVID-19 vaccine considered safe during pregnancy by ACOG?
Yes. ACOG maintains that the COVID-19 vaccine is safe and effective, recommending it be administered as soon as possible during pregnancy, regardless of the trimester.
Did you know? ACOG’s decision to issue this independent schedule is supported by 13 other medical societies, including the National Association of Nurse Practitioners in Women’s Health, signaling a unified front among specialists in women’s health.
