A recent small study points out that the Covid-19 vaccine could have an impact on their mentruations.
Nothing has been proven for the moment, because the question has not been really studied. But several observations have been made around side effects on the menstruation of women vaccinated against Covid-19, explained last May. BBC Africa. More recently, the pharmacovigilance point of the Medicines Agency (ANSM) reported rare cases of menstrual disturbances occurring after vaccination, with Moderna (36 cases out of 6.4 million injections) and Pfizer (229 cases out of 53 million injections).
“This potential signal will be brought to the European level”, explains the ANSM press release concerning this side effect of the vaccine, which has an impact on the periods of people who have received one or two doses of Pfizer or Moderna. She specifies, however, that these are not “serious” or even worrying effects: rules that are sometimes delayed, in some cases absent, or at least unusual. Attention will be paid to these cases to try to understand if there is a link with the vaccine.
Bleeding in people who have had their period more
Women have observed heavier and sometimes more painful periods after vaccination. This was explained in a Womanizer survey of its panel of menstruating testers last May. Out of 552 people, with one or two doses of the vaccine, one in five people noticed an effect on their menstrual cycle. 31% had stronger periods, 29% had more pain, 22% observed an unusual delay.
From transgender people who were no longer dead after taking hormones found bleeding after the vaccine. Postmenopausal women have also made this observation. A specialist from Imperial College London, Dr Victoria Male, believed that the vaccine and menstrual changes could therefore be linked.
Immune reaction and inflammation?
One of the reasons that could explain it would be an immune reaction. Moreover, in an article on the question, The Parisian of August 1 quotes Olivier Picone, gynecologist-obstetrician at the Louis-Mourier hospital in Colombes and member of the National College of French Gynecologists and Obstetricians (CNGOF), who supports this theory. With the vaccine, “the immune system is stimulated and will secrete proteins. But if they are secreted at too high a level, they will be able to disrupt the communication between the ovary and the hypothalamic-pituitary axis and therefore modify the menstrual cycle, “he explains daily. He reminds us that the menstrual cycles are very receptive to all the daily changes.
According to other explanations provided by the Womanizer study, immune cells are found in the lining of the uterus, and changes in these cells following the vaccine could lead to more bleeding. On the other hand, the vaccine has already been found to cause inflammation of the body, again the uterus could be impacted.
That said, doctors who have looked into the matter believe that this reaction is not strong enough to cause a miscarriage, for example. If nothing has been proven for the moment, the observation of these reactions shows that these effects are temporary, on the one hand, safe on the other. No long-term repercussions are to be feared, nor even a risk of infertility, Olivier Picone explains to the Parisian.
