What the records do raise are questions about how uncertainty was communicated to Americans during the earliest months of the vaccine rollout.
Fauci’s Private Exchange Raises New Questions
On January 25, 2021, Dr. John Mascola, then director of the Vaccine Research Center at NIAID, discussed pregnancy and the vaccine with Fauci.
According to the newly released records, Mascola wrote:
“Initial Studies avoid vaccination in first trimester due to possible fever and higher rates of miscarriage in first trimester,”
Fauci responded by acknowledging a theoretical concern connected to post-vaccination fever:
“Since many people have significant cytokines storm and fever after the 2nd dose, this theoretically could be associated with miscarriage in the 1st trimester,”
The language matters.
Fauci was discussing a theoretical possibility, not reporting evidence that vaccines were causing miscarriages. Early clinical trials also had limited pregnancy data, leaving officials to make recommendations while evidence was still developing.
Yet only days later, Fauci’s public message sounded considerably more reassuring.
During a February 3 JAMA livestream, Fauci discussed the available information on pregnant women receiving the vaccines and said regulators had seen no concerning safety signal.
That gap between private scientific caution and public reassurance is now attracting attention on Capitol Hill.
FDA Official Privately Sounded Another Alarm
Another newly disclosed communication shows that concerns about adverse-event monitoring reached Fauci several months later.
Then-Acting FDA Commissioner Janet Woodcock wrote to Fauci and then-NIH Director Francis Collins on May 27, 2021, describing reports she had received from healthcare professionals about lingering medical problems following vaccination.
“The peoples’ main complaint is that no one takes them seriously, no one knows how to treat them, and there is no effort to study this,” Woodcock wrote.
Woodcock also questioned whether existing surveillance systems were equipped to identify the types of problems being described.
“These problems are not the sort that a system like VAERS would be able to detect,”
Fauci apparently recognized that Woodcock’s concerns warranted attention.
“We cannot ignore her.”
The newly released correspondence indicates Fauci forwarded the matter to Collins and suggested bringing the CDC into the discussion. The records therefore do not support the stronger claim that Fauci simply received Woodcock’s warning and literally “did nothing,” although Republicans are questioning whether the government’s subsequent response was adequate.
Fauci Pleads The Fifth More Than 100 Times
The documents are surfacing amid a much larger confrontation between Fauci and Senate Republicans.
Fauci appeared before the Senate Homeland Security and Governmental Affairs Committee on July 29 and repeatedly invoked his Fifth Amendment protection against self-incrimination.
His response throughout the hearing was essentially the same:
“On the advice of counsel, I respectfully decline to answer based upon my rights under the Fifth Amendment to the Constitution,”
He invoked the Fifth more than 100 times.
Fauci has argued that he has legitimate reason to fear prosecution because Sen. Rand Paul and other Republicans have openly accused him of wrongdoing. His attorneys characterize the congressional investigations as politically motivated harassment.
Republicans see things very differently.
They argue that former President Joe Biden’s sweeping preemptive pardon of Fauci, covering federal offenses from January 1, 2014 through January 19, 2025, undermines Fauci’s justification for refusing to answer questions about conduct during that period.
The constitutional dispute is not as simple as saying the pardon automatically eliminates Fauci’s Fifth Amendment rights, however. Legal experts have raised questions about potential exposure stemming from new testimony, including possible false-statement or perjury allegations.
Senate Panel Moves Against Fauci
The standoff escalated on August 6.
The Republican-controlled Homeland Security Committee voted 8-7 along party lines to advance a contempt resolution against Fauci. Paul subsequently asked the Justice Department to pursue criminal contempt charges.
Whether that referral can produce a prosecution remains disputed. Critics argue that bypassing a vote of the full Senate creates serious procedural problems for any potential criminal case.
Fauci has since declined another request to voluntarily appear before a separate Senate panel led by Sen. Ron Johnson.
The result is a confrontation that is no longer simply about disagreements over pandemic policy.
Republicans now have Fauci’s private communications, his pandemic-era records and years of public testimony to compare side by side.
And the January 2021 exchange gives investigators another line of inquiry: exactly what did Fauci know about the uncertainties surrounding vaccination during pregnancy, when did he know it, and how accurately did his public statements reflect those uncertainties?
The released messages don’t prove that vaccines caused miscarriages.
But they do show that, behind closed doors, Fauci was considering a theoretical first-trimester risk at a moment when millions of Americans were depending on federal health officials to communicate not only what they knew — but what they still didn’t know.
