Doctors are seeking further research on whether COVID-19 (New Coronavirus Infection) The vaccine causes a change in duration after thousands of women report irregular menstrual cycles after firing.
Dr. Victoria Male, Lecturer of Reproductive Immunology at Imperial College LondonSaid last year’s clinical trials should have looked for abnormal menstruation.
At least 6,000 women in the United States report that their period was faster, heavier, or appeared irregular after vaccination.
In addition, more than 35,000 women in the UK complain of suffering from menstrual irregularities.
Authorities have not yet confirmed a link between firing and an irregular cycle, but men have a large number of immune cells in the uterus that are activated by the vaccine and cause irregular bleeding. He said it could cause it.
She added that investigating such links could help prepare women for the possibility of irregular cycles and increase shot confidence.
“Vaccine hesitation among young women is mainly caused by false claims that the COVID-19 vaccine can impair the chances of future pregnancy,” the man writes. BMJ..
“Failed to thoroughly investigate reports of changes in menstruation after vaccination can fuel these fears.”
More than 6,000 women in the United States report to the CDC reporting system after Covid vaccination that they are heavier than the normal or abnormal menstrual cycle.

According to the Daily Mail.com analysis of the Centers for Disease Control and Prevention (CDC) Vaccine Adverse Event Reporting SystemThere were at least 6,047 reports of US women reporting abnormal menstrual cycles.
However, this can be a serious underestimate, as most women who experience abnormal menstruation do not report to the CDC.
The most common complaint is severe menstrual bleeding by 2,571 women reporting this condition as of Thursday.
Other frequent reports include irregular menstruation, menstrual bleeding, delayed menstruation, and abnormal uterine bleeding.
However, some women experience less common symptoms, such as the anovulatory cycle, in which the ovaries do not release eggs, and the overovulation that occurs when a woman releases multiple eggs per month. ..
Earlier, CDC officials stated that none of the reports justified their concerns.
“At this time, the CDC is unaware of any safety concerns that justify additional monitoring of irregular menstrual symptoms reported to the Vaccine Adverse Event Reporting System,” a spokeswoman for the CDC Vaccine Task Force said. One Martha Sharan said in an email. Chicago Tribune..
She added that the report constitutes a “very small number” of more than 300 doses administered in the United States.
However, there is sufficient concern that the National Institutes of Health (NIH) will grant grants to five universities earlier this month to study whether there is a link between abnormal menstruation and the COVID-19 vaccine. I have.
Five studies could recruit 400,000 to 500,000 participants, including adolescents, transgender women, and non-binary people.
According to NIH, there are several factors that can cause Covid immunity to cause transient changes in the menstrual cycle.
This includes pandemics, lifestyle changes, and even the stress associated with previous COVID-19 infections.
NIH also suggests that the immune system’s response to the COVID-19 vaccine may temporarily affect communication between immune cells and the uterus.
Gynecologists have previously told the DailyMail.com that post-vaccination cycle changes can occur, but they are rare and usually resolve spontaneously without medication and affect childbirth. Does not give.
In the UK, more than 35,000 women are in the country Yellow Card Scheme of Pharmaceutical and Medical Product Regulators Suffering from an irregular cycle after vaccination.
Dr. Jackie Mavin, an obstetrician and gynecologist and senior clinical researcher at the University of Edinburgh, said other vaccines, such as the HPV vaccine, are known to disrupt duration without noticeable impact on childbirth. rice field.
‘At this stage, it is difficult to identify the mechanism that causes these effects.It may vary from person to person, “she said. statement To the Royal College of Obstetrics and Gynecology.
Mabin also suggested that stress plays a role-explains that stress on the body interferes with pregnancy and saves energy.
“This effect at the brain level may explain some of the changes in menstruation observed with Covid or vaccination during the pandemic,” Mavin said.
She added: ‘The resulting inflammation can temporarily affect the ovaries, alter hormone production over a cycle of 1-2 cycles, and cause irregular or heavier menstrual bleeding.
“Inflammation can also temporarily change the way the lining of the uterus breaks and falls off, causing a heavier period.
“These effects can lead to temporary changes in menstrual symptoms that should resolve spontaneously.”
