A new study has found that a majority of women experienced changes to their menstrual cycles after being injected with COVID-19 vaccines, with over 40% of women saying vaccines preceded heavier periods.
The study from the Science Advances journal revealed that 42%, nearly half of women, who received COVID-19 vaccines, experienced heavier periods following their vaccination. 14% of women reported a lighter period post-vaccination, with 44% reporting no change.
The study also found that many non-menstruating women – women who are menopausal or using certain long-term contraceptives – were also reported to have experienced “breakthrough or unexpected bleeding after their Covid shots.”
The survey was conducted with over 39,000 vaccinated women ages 18 to 80 years old who had not contracted coronavirus. The respondents had reportedly been injected with Pfizer, Moderna, AstraZeneca, Johnson & Johnson and Novavax vaccines.

“Before the vaccinations came out, I would say our knowledge on the subject of the connection between immunization and menstrual changes, in general, was nil,” said the National Institute of Child Health and Human Development’s Candace Tingen.
“It was really this lack of information that I think caused confusion, fear and perhaps vaccine hesitancy,” she added.
The U.S. Centers for Disease Control and Prevention (CDC) as of yesterday maintains that there is “no evidence that COVID-19 vaccines affect fertility.”
However, the National Institutes of Health (NIH) in previous research has noted that “fertility depends on the menstrual (ovarian) cycle, and in each cycle there is a ‘fertile window’ during which women can conceive.”
NBC noted that very few studies exist that assess the direct effect of COVID-19 vaccination on the menstrual cycle and most Big Pharma vaccine trials did not included inquiries about menstrual changes.
“It was really this lack of information that I think caused confusion, fear and perhaps vaccine hesitancy,” Tingen said.

The revelation comes after CDC Director Rochelle Walensky on Tuesday claimed that many once “fully vaccinated” Americans are now considered to be “undervaccinated” because they have not received enough COVID-19 “booster” injections.
“Many Americans are undervaccinated,” Walensky said. “Meaning, they are not up to date on their COVID-19 vaccines.”
U.S. health officials continue to issue their concerns over COVID-19 Omicron subvariants, such as BA.5 which is apparently set to cause a “new wave” of infections in the United States despite hundreds of millions of people having been vaccinated against the virus.
During a Wednesday appearance on CNN, Biden administration medical advisor Dr. Anthony Fauci declared that Americans “really should” wear face masks again in “congregate” and “indoor” settings due to the rise in cases.
“You really should, in an indoor setting, a congregate setting, be wearing masks,” Fauci said. “It’s just the appropriate thing to do.”
