The top professional organization for OB-GYNs in the United States just did something it has never had to do before: publish its own vaccination schedule for pregnant women, independent of the federal government, because the federal government has stopped being trustworthy on the subject. This is not a minor professional disagreement. This is the medical establishment formally announcing that Washington, under Robert F. Kennedy Jr., has lost the plot.
What Actually Happened Here
The American College of Obstetricians and Gynecologists, known as ACOG, released its first-ever official maternal vaccination schedule last week, recommending four vaccines for all pregnant people: flu, Covid, Tdap, and RSV. For patients with certain risk factors, hepatitis B and MMR may also be recommended. Thirteen medical societies co-signed it, including the American Academy of Pediatrics and the American Academy of Family Physicians.
To be clear about what this represents: ACOG has long recommended these shots. The difference now is that they felt compelled to formalize it into a standalone schedule, one designed to reach not just providers but patients and pharmacists directly. According to The Guardian, the explicit goal was to "address the growing vaccine misinformation that is circulating." They didn't name RFK Jr. in that sentence. They didn't have to.
Until 2025, ACOG's recommendations were, in their own words, "in sync" with the CDC. Then Kennedy took over HHS, and the sync broke. In early 2026, ACOG withdrew entirely from the Advisory Committee on Immunization Practices, citing what Christopher Zahn, ACOG's chief of clinical practice, described as "concerns about recent changes that undermine the committee's scientific integrity and evidence-based approach to vaccine policy." Polite language for: we will not put our name on whatever this has become.
The Administration's Record on Maternal Vaccines Is a Disaster
Under Kennedy's direction, the Trump administration dropped its recommendations for flu and Covid shots during pregnancy. The ACIP, which advises the CDC, was preparing to take up vaccines for pregnant people as its next agenda item before a judge's order halted the committee entirely. So the process for updating federal guidance on pregnancy vaccines has been, depending on how you count, either corrupted or frozen solid.
Then there's the RSV situation. Tracy Beth Høeg, a sports medicine physician who was overseeing vaccine investigations at the FDA until she was fired in May, publicly claimed without rigorous supporting data that the RSV vaccine was deadly for babies. That claim spread. It did damage. The first real-world U.S. data study on RSV vaccination during pregnancy, published last week in JAMA Network Open, found the vaccine is 68% effective at preventing hospitalization in infants under three months old. Sixty-eight percent. Effective. Against hospitalization. In newborns.
Laura Riley, chair of obstetrics and gynecology at Weill Cornell Medicine and a member of ACOG, was blunt at the press conference announcing the schedule. "The evidence does not support their recommendation," she said of the administration's position. "The evidence supports our recommendation." When prominent academic physicians start holding press conferences to contradict the sitting Secretary of Health and Human Services, something has gone badly wrong.
The Babies Are the Ones Who Pay
Here is the part that should make you sit with it for a second. Babies cannot be vaccinated against most of these diseases for months after birth. Their protection during that window depends almost entirely on the immunity their mothers pass on during pregnancy. This is not a controversial medical position. It is how immunology works.
Andrew Racine, president of the American Academy of Pediatrics, said it plainly to The Guardian: "Babies are among the most susceptible populations for vaccine-preventable diseases, and they depend upon the adults around them to keep them safe in those first few months of life before they've had the opportunity to develop their own immunity." Maternal vaccines, he said, are a "key element" of that protection.
Riley separately pointed to "very clear data" that Covid vaccines during pregnancy reduce hospitalization and preterm birth. Preterm birth. We're not talking about theoretical future risks. We are talking about measurable, documented harm to infants happening right now as vaccine hesitancy climbs. According to The Guardian, the flu vaccination rate among pregnant people has fallen to around 30%, and Covid vaccination rates are even lower. Seventy percent once got their Tdap and RSV shots. That was before Kennedy started running things.
The Misinformation Problem Is Getting Worse Fast
Providers are watching vaccine hesitancy climb in real time. Racine told The Guardian that hesitancy among parents is significantly higher than it's ever been and that it is "taking a significant toll" on pediatric practices. The dynamic feeding it is not subtle: patients come in having done their own research, which in 2026 means they watched something on TikTok or read a Substack from someone who got fired from the FDA.
Sarah Vaillancourt of the National Association of Nurse Practitioners in Women's Health acknowledged the social media problem directly, noting that it isn't going away and asking how clinicians help patients find accurate information when the federal government is no longer reliably providing it. That question is not rhetorical. It is a genuine operational crisis for people trying to practice evidence-based medicine.
There's also a disparity angle here that deserves more attention than it gets. Kevin Ault, a professor of obstetrics and gynecology at Western Michigan University, told The Guardian that vaccination rates differ between people on public versus private insurance, and those gaps track with disparities in outcomes for babies. The people most likely to be left behind as the information environment degrades are the people who already face the highest barriers to care.
What ACOG Is Actually Asking Doctors to Do
The new schedule recommends flu and Covid vaccines in any trimester. Tdap between weeks 27 and 36. RSV between weeks 32 and 36. The guidance was informed by a comprehensive review from the Vaccines Integrity Project, per The Guardian, and is designed to be something a patient can actually read and understand, not just a directive handed down through clinical channels.
The goal is to give providers, pharmacists, and patients a single authoritative document they can point to when someone walks in carrying a screenshot of something a wellness influencer posted. "The science is clear," said Margot Savoy, chief medical officer of the American Academy of Family Physicians. Vaccines in pregnancy provide "critical protection." She did not add qualifications. She did not hedge. She said it because it is true and because somebody in an official capacity needs to keep saying it.
The Dingo Take
Let's be precise about what we are watching happen. The leading OB-GYN organization in the United States spent decades working inside the federal recommendation process. It had seats on the committee. It had influence. It contributed to policy. Then Robert F. Kennedy Jr. took over HHS, gutted the scientific advisory infrastructure, dropped evidence-based vaccine guidance for pregnant women, and allowed a fired sports medicine physician to publicly claim without good data that an RSV vaccine kills babies. So ACOG left. And then it built its own table.
This is what institutional collapse looks like from the inside. It doesn't announce itself with a single dramatic moment. It looks like a respected medical organization quietly deciding they can no longer function within a federal system and having to stand up a parallel guidance structure to fill the void. Thirteen other medical societies signed onto that structure within days. That is not a protest. That is a succession plan.
The people who will pay the most for this are the ones who always pay. Pregnant women in rural areas with limited access to specialists. Low-income patients on Medicaid. People who rely on federal guidance because they don't have a doctor who will sit down and walk them through the research. They will encounter the Kennedy-era CDC's recommendations, or a social media post that's even worse, and they will make decisions based on it. Some of those decisions will hurt their babies. That is not hyperbole. That is what the data already shows is starting to happen, and we are only in year two.
