The Senate Committee on Health, Education, Labor and Pensions released text messages Monday showing Dr. Anthony Fauci privately discussed a theoretical concern that fever and other reactions following a second COVID-19 vaccine dose could be associated with miscarriage in the first trimester.
The January 2021 conversation was obtained from Fauci's government-issued cellphone. The former director of the National Institute of Allergy and Infectious Diseases wrote in the exchange that the reaction "theoretically could be associated with miscarriage in the 1st trimester." The texts also show Dr. Vivek Murthy, who later served as former President Joe Biden's surgeon general, weighing in on the discussion about how to handle vaccine recommendations for pregnant women.
Sen. Rand Paul, R-Ky., and Sen. Ron Johnson, R-Wis., released the text messages publicly. Both senators have been critical of Fauci's handling of the pandemic response throughout the investigation.
What the Left Is Saying
Democratic lawmakers and public health experts argue that the texts reflect standard scientific deliberation rather than evidence of wrongdoing. They note that raising theoretical concerns in private while communicating based on available data publicly is a normal part of medical decision-making.
At the time of these messages, data on COVID-19 vaccines and pregnancy was limited. The Centers for Disease Control and Prevention ultimately studied the issue extensively and found no increased risk of miscarriage associated with vaccination. Multiple studies published since have confirmed the safety of mRNA vaccines during pregnancy.
Public health advocates argue that Fauci was appropriately consulting with colleagues about potential risks as new information emerged, a process they say is essential to good medical science. They note that theoretical concerns raised in internal discussions are not the same as confirmed dangers and that public health officials must communicate based on evidence while continuing to investigate unknowns.
Progressive commentators have pointed out that the texts show Fauci doing exactly what health experts should do: raising potential concerns for investigation while avoiding undue alarm before evidence supports a change in guidance. They argue that critics who now claim miscarriage risks were hidden had access to the same limited early data that Fauci and other officials were working with at the time.
What the Right Is Saying
Republican lawmakers and conservative commentators have sharply criticized the texts, arguing they show Fauci publicly downplaying concerns he privately acknowledged could be significant.
Sen. Rand Paul said on social media: "Once again, Anthony Fauci was saying one thing in public and something completely different in private. He was willing to put women and their unborn children at risk instead of admitting that he was wrong about the vaccines that he tried guilting Americans into taking."
Florida Attorney General James Uthmeier accused Fauci of withholding information: "Pregnant women were told it was safe! How many women lost babies due to Dr. Fauci's lies," he posted on social media.
Former Rep. Marjorie Taylor Greene, R-Ga., called for criminal prosecution: "Fauci knew Covid shots cause miscarriages. And still forced the shots. Fauci belongs in prison," she wrote, adding in a separate post: "If a Covid vaccine can kill a baby and cause a miscarriage, then imagine all the other things it can do to you. And Fauci knew it and still told people to take it."
Sen. Johnson's office released a statement saying the findings "could have an immediate impact on public health and the principle of informed consent," arguing that pregnant women deserved to know about even theoretical risks when making vaccination decisions.
What the Numbers Show
According to CDC data analyzed after the initial vaccine rollout, studies found no increased risk of miscarriage associated with COVID-19 mRNA vaccines. Research published in peer-reviewed journals including the New England Journal of Medicine and JAMA examined thousands of pregnant women who received vaccinations during pregnancy.
At the time of the January 2021 texts, more than 10,000 pregnant women had already been vaccinated according to data available to officials, with no widespread safety signals reported at that point. The World Health Organization initially recommended against Moderna's vaccine for pregnant women due to limited data, though it later updated guidance as evidence accumulated.
The CDC's current guidance states that COVID-19 vaccination is recommended for people who are pregnant, breastfeeding, or trying to get pregnant now or in the future. Multiple studies have also examined immune responses and outcomes for infants born to vaccinated mothers.
The Bottom Line
The release of these texts adds another chapter to the ongoing political debate over pandemic-era public health decisions. Critics argue that even theoretical concerns warranted more transparent communication with the public, while supporters say private scientific deliberation should not be conflated with confirmed risks.
The controversy highlights broader questions about informed consent and how public health officials should communicate uncertainty during evolving medical situations. Senate investigators have been examining Fauci's communications for months as part of their oversight review of pandemic response policies.
What to watch: The Senate committee investigation is ongoing, and additional communications may be released. The texts could factor into future legislative debates about pandemic preparedness authority and transparency requirements for federal health officials.
