Chia-Yi Hou with The Hill compiled the findings of multiple peer-reviewed studies analyzing “women who reported experiencing changes in their menstruation after they got COVID-19 or were vaccinated against it.” Here are some of the findings:
A study of almost 4,000 women in the U.S. found that menstrual cycle lengths were extended by about 0.7 days after a first dose and 0.9 days after a second dose of a COVID vaccine. Though the cycles were longer overall, researchers did not find a change in how many days women’s periods lasted. The study was published in Obstetrics & Gynecology.
Moreover, a new publication in the Journal of Infection and Chemotherapy also found that COVID vaccination may affect menstrual cycle length in women. The study analyzed data from women in Japan, comparing predicted and actual menstrual cycle lengths before and after vaccination. The results revealed that on average, the difference in menstrual cycle length increased by 0.6 days after one dose of the vaccine and by 0.6-1 days after two doses of the vaccine. The change was more significant among women who received two doses within the same menstrual cycle, with an average difference of 3.9 days.
Finally, a study of 5,000 women in six Arab countries found that vaccinated individuals had more frequent back pain, nausea, tiredness, pelvic pain, and passage of loose stools in connection with their menstruation compared to unvaccinated individuals. Vaccinated people also reported experiencing heavier flow and more days of bleeding. The paper was published last month in Influenza and Other Respiratory Viruses.
“Reproductive toxicology has not been undertaken with any of these products,” Dr. Michael Yeadon, the former Vice President and Chief Scientist for Allergy and Respiratory research for coronavirus vaccine maker Pfizer Inc., said of COVID vaccines, American Faith reported in Aug 2021.
“Here we are dosing potentially hundreds of millions of women of childbearing potential with products which are untested in terms of impact on fertilization and development of the baby,” Dr. Yeadon said at the time.
Yeadon cited a Freedom of Information Act (FOIA) request that brought to light a report showing the coronavirus vaccine distributes around the bodies of rats, instead of “mostly remain[ing] near the site of injection.”
“To my horror, what we find is the vaccine doesn’t just distribute around the body and then wash out again,” he said. Rather, it “concentrates in ovaries of rats. And it concentrates at least twenty-fold over the concentration in other background tissues like muscles.”
“My assumption at the moment is that’s what’s happening to every female who’s been given these vaccines. These vaccines are concentrating in her ovaries,” Yeadon went on to say. “We don’t know what that will do, but it cannot be benign, because the vaccines will then express the coronavirus spike protein and we know that there are unwanted biologies from that spike protein.”
Yeadon also cited a study showing 15 women who were given the Pfizer vaccine “measured antibodies against the placenta”—in addition to antibodies against the spike protein—with a “300% increase” in the “first four days.”
“That is a vaccine-induced autoimmune attack on their own placenta,” said Yeadon. “You can only expect that is happening in every woman of childbearing potential.”
“You can’t get pregnant and have a successful pregnancy if this protein is damaged in any way” because the protein is “essential” for “both fertilization and formation and maintenance of the placenta,” according to Yeadon.
“What this vaccine has done is induced an autoimmune response,” he explained. “I’m here to warn you that if you are of childbearing potential or younger, I would strongly recommend you do not accept these vaccines.”
Today, the Centers for Disease Control and Prevention (CDC) maintains “COVID-19 vaccines are safe and effective and severe reactions after vaccination are rare,” according to the agency’s website.
