Newly leaked text messages have thrust Dr. Anthony Fauci back into the firing line, revealing the nation’s former top health official was privately warned about miscarriage concerns relating to COVID vaccines.
During the early days of the vaccine’s release, then director of the Vaccine Research Center, Dr. John Mascola, fired off a message that has now landed at the center of a Republican Senate investigation.
‘I am corrected on pregnancy studies,’ Mascola wrote to Fauci via text message. ‘Initial Studies avoid vaccination in first trimester due to possible fever and higher rates of miscarriage in first trimester.’
Data pulled from Fauci’s iPhone shows he opened the message that same evening, within an hour of receiving it, according to metadata released by Republican Senator Ron Johnson.
There’s no indication Fauci responded to the text.
What the subcommittee still cannot answer is the most explosive question of all: what ‘initial studies’ Mascola was referring to, or why he sent the message in the first place.
Johnson’s office said it emailed Mascola immediately demanding answers, only to be met with silence after the former NIAID scientist retained an attorney.
Johnson has since accused federal health officials of stonewalling the American public for years, and says he hopes Mascola will finally break the pattern and cooperate.

The revelation piles yet more pressure on Fauci, whose reputation has been battered by allegations of a Wuhan lab leak cover-up, an indicted former adviser, and mounting Republican calls for prosecution despite his preemptive pardon from Biden.
On August 10, Johnson and Rand Paul dropped the first batch of texts pulled from Fauci’s government iPhone, which included more than 34,000 messages and 522 voicemails.
In a January 2021 exchange with then-CDC director Rochelle Walensky and future Surgeon General Vivek Murthy, Fauci flagged that many people suffer cytokine storms and fever after the second dose.
That reaction, he warned, ‘theoretically could be associated with miscarriage in the 1st trimester.’
In another text message, Murthy asked Fauci and Walensky if they had seen a WHO advisory, ‘against pregnant women taking the Moderna vaccine bc of lack of data?’
‘It has led to a flurry of questions. What is your take? I imagine we will all get asked about this,’ Murthy probed his colleagues.
Fauci responded that ‘[with regard to] pregnant women one must weigh the potential risks against the benefits,’ of getting the vaccine versus COVID itself, before adding that ‘animal tox studies did not raise any red flags.’
Murthy then indicated that the WHO statement was a ‘strong [one] to make’ and ‘potentially quite damaging to public confidence among pregnant women.’
Paul seized on the messages to accuse Fauci of privately admitting concerns while publicly telling Americans there was nothing to worry about.
Fauci said in February 2021 there were “no red flags of anything that anyone would be worried about” among vaccinated pregnant women.
By August 2021, the CDC explicitly recommended vaccination during pregnancy after accumulating data found no increased miscarriage risk.
Earlier this month, Fauci was found in contempt of Congress and could now be referred to the Department of Justice for prosecution.
GOP lawmakers had probed him about his time as the nation’s leading infectious disease specialist, and the guidance he recommended during the COVID-19 pandemic.
Fauci invoked the Fifth Amendment 111 times under questioning from senators.
