A new study shows that the COVID-19 vaccine does not interfere with women’s periods.
Research led by the University of Edinburgh has found that infection with the virus can lead to changes such as missed or increased periods, or bleeding between periods.
about one fifth vaccination Women report changes in periods Coronavirus Jab, according to research.
But the study also found that the vaccine didn’t appear to be effective when comparing vaccinated and unvaccinated people.
Here’s what the research found
Researchers survey nearly 5,000 premenopausal vaccinated people female March 2021 in the UK.
It was found that 82 percent of the women reported no menstrual changes.
While 6.2 percent reported more interruptions in their menstrual cycle, 1.6 percent reported fewer interruptions.
About 10 percent reported changes, including cycle length and regularity, and menstrual flow.
Women who reported a change (18%) were at higher risk because they smoked, had a previous COVID-19 infection, or were not using estradiol-containing contraceptives such as the combined contraceptive pill.
The researchers also looked at a wider group of 12,579 vaccinated and unvaccinated women.
The group included 3,635 vaccinated women who had never been infected with COVID-19 and 1,354 women who had been infected with the virus.
The study also looked at 1,802 women who had had the virus in the past but were not vaccinated, and 5,788 women who were neither vaccinated nor diagnosed with COVID-19.
So, how did it turn out?
It was found that vaccination alone did not lead to increased menstrual variability.
However, those with a history of viral illness reported an increased risk of heavy bleeding, missed periods, and intermenstrual bleeding.
Dr Jackie Maybin, one of the study authors, from the University of Edinburgh, said: “These results relied on people recalling their previous menstrual experiences, and may include bias due to the choice of who completed the survey.
“Nevertheless, our results are reassuring that COVID-19 vaccination does not cause menstrual changes and help identify individuals who may be at higher risk for menstrual disturbances.”
