Five institutions will explore potential links between COVID vaccines and menstrual irregularities — research that wasn’t conducted during clinical trials, but is being done now, after thousands of women reported changes in their menstrual cycles post vaccination.
The National Institutes of Health (NIH) has awarded one-year supplemental grants totaling $1.67 million to five institutions to explore potential links between COVID vaccines and menstrual changes, after thousands of women reported menstrual irregularities after vaccination.
According to the NIH website, some women have reported experiencing irregular or missing menstrual periods, heavier-than-usual bleeding and other menstrual changes after receiving COVID vaccines.
The new funding will go toward research to determine whether the changes may be linked to COVID vaccination itself, and how long the changes last. Researchers will also seek to clarify the mechanisms underlying potential vaccine-related menstrual changes.
The year-long study will initially follow unvaccinated participants to observe changes that occur following each dose. Some groups will exclude participants on birth control or gender-affirming hormones, which may have their own impact on periods.
Researchers will assess the prevalence and severity of post-vaccination changes to menstrual characteristics, including flow, cycle length, pain and other symptoms. These analyses will account for other factors that can affect menstruation — such as stress, medications and exercise — to determine whether the changes are attributable to vaccination.
The five NIH-funded studies will be conducted by researchers at Boston University, Harvard Medical School, Johns Hopkins University, Michigan State University and Oregon Health and Science University.
The studies will likely incorporate between 400,000 and 500,000 participants –– including adolescents and transgender and nonbinary people, according to Dr. Diana Bianchi, director of the agency’s Institute of Child Health and Human Development, which is funding the research along with NIH’s Office of Research on Women’s Health.
“Nobody expected it [vaccination] to affect the menstrual system, because the information wasn’t being collected in the early vaccine studies,” said Bianchi, who credited The Washington Post’s early coverage of the issue, in April, with first making her and her staff aware of it.
These “rigorous scientific studies will improve our understanding of the potential effects of COVID-19 vaccines on menstruation, giving people who menstruate more information about what to expect after vaccination and potentially reducing vaccine hesitancy,” Bianchi added.
So far, no published studies have examined — or offered conclusive evidence — of possible links between the vaccines and menstruation.
The COVID vaccine trials did not specifically ask participants whether they saw adverse side effects in their menstrual cycles or volumes — an omission Bianchi attributes to the fact “the Emergency Use Authorization was really focused on critical safety issues” and “changes to your menstrual cycle is really not a life and death issue.”
But the lack of formal research on the potential link between the two “points out the fact that safety studies for vaccines … are not necessarily thinking about the reproductive health of women,” Bianchi said. “We hope one of the things that’s going to come out of this is that questions will be added to clinical trial studies to include any changes in menstrual health.”
According to the NIH, numerous factors can cause temporary changes in the menstrual cycle, which is regulated by complex interactions between the body’s tissues, cells and hormones.
Immune responses to a COVID vaccine could affect the interplay between immune cells and signals in the uterus, leading to temporary changes in the menstrual cycle.
Menstrual changes after COVID vaccination also could be attributed to immune responses to the vaccines and their impacts on the uterus, as well as to pandemic-related stress, lifestyle changes and the virus itself.
The new studies will build on existing research and leverage data from menstrual tracking applications to evaluate the potential impacts of COVID vaccination on menstrual health among geographically and racially and ethnically diverse populations.
The researchers hope that, following a peer-review process, findings will be published by the end of 2022 or soon after.
As The Defender reported, researchers have called for clinical trials since April to track and document menstrual changes in vaccinated women after some women reported hemorrhagic bleeding with clots, delayed or absent periods, sudden pre-menopausal symptoms, month-long periods and heavy irregular bleeding after being vaccinated with one or both doses of a COVID vaccine.
According to the most recent data from the Vaccine Adverse Event Reporting System (VAERS) — the primary government-funded system for reporting adverse vaccine reactions in the U.S. — between Dec. 14, 2020 and Aug. 27, 2021 — there have been 7,963 total reports of menstrual disorders after vaccination with a COVID vaccine.






Egg thrown at California governor candidate Larry Elder in ‘racist’ attack
California Republican gubernatorial candidate Larry Elder got a hostile reception as he toured a Venice homeless encampment Wednesday — with one woman in a pink gorilla mask chucking an egg that narrowly missed the radio talk show host’s head.
The attacker, who was spotted on video tweeted by Spectrum News reporter Kate Cagle, was seen in all black steering her bike into position a few feet from Elder’s left shoulder before letting fly with the missile.
The gorilla mask spurred charges that the attacker was “racist.”
“A blatant racist wearing a gorilla mask attacked @larryelder these people are completely unhinged,” former Republican candidate for the Virginia House of Delegates, Jeffrey A. Dove Jr., tweeted.
“That’s all you say about this violence? It was more than a flying egg – these Left wing racists were attacking a black man running for Governor,” Richard Grennell tweeted, while sharing Cagle’s video of the incident. “Why is Spectrum One dismissing racist attacks?”
Matt Gorman, the former communications director for the NRCC, seemingly called out the left for their lack of outrage over the incident.
“If someone in a gorilla costume threw an egg at a black *Democratic* candidate, every GOPer in the country would be getting asked to comment,” he tweeted.
When the woman was confronted by a member of Elder’s security team, she told him to “take your hands off me, motherf—er! Touch me again! Touch me again!” She then aimed a left hook at the man, leading others to step in and break up the confrontation.
The security guard was then menaced by another man wearing all black before a second woman slapped him on the side of his head. As the Elder team member was led away, the candidate was hustled into a white SUV. Someone from the crowd yelled to “get that piece of s–t out of here” as the vehicle pulled away.
The Los Angeles Times estimated that Elder spent 12 minutes in Venice before his visit was cut short by the ugly incident. Sarah Duke, a pregnant homeless woman who lives in the encampment the candidate was visiting, told the paper that Elder “has no business down here.”
“If you ain’t going to help us, move … on,” Duke added.
Elder, who had cast his ballot in the Sept. 14 recall election earlier Wednesday, later tweeted that he had kicked off his “Recall Express” bus tour with the visit to Venice.
“Before we even left Los Angeles, my security detail was physically assaulted, shot with a pellet gun, and hit with projectiles,” he wrote. “The intolerant left will not stop us. We will recall Gavin Newsom. We will save California.”
Elder is one of 46 candidates on the ballot in next week’s election — the second such vote to take place in California in under two decades. Voters who fill out a ballot will first be asked whether Newsom, a Democrat, will be recalled. If a simple majority votes “yes,” whichever of the 46 contenders gets the most votes will take his place as governor.
Campaigners hoping to recall Newsom face an uphill effort, if the latest polling is any indication. An average of surveys from the website FiveThirtyEight shows support for keeping Newsom in office to be 12.3 percentage points higher than support for removing him.
The incumbent was boosted Wednesday by high-profile support from Vice President Kamala Harris, a fellow Bay Area native who joined Newsom at a rally in San Leandro, just south of her hometown of Oakland.
