On Twitter, Debout La France MP Nicolas Dupont-Aignan shared a study by the National Institute of Health, the American equivalent of Inserm, which looked at the possible link between vaccination and menstrual disorders. Troubles that, according to Nicolas Dupont-Aignan, “many women” reported “since the start of the vaccination campaign”.
>> TRUE OR FAKE: does the Covid-19 vaccine cause late periods?
“Who listened to them?”questions the former presidential candidate, thus implying that these testimonies would not have been taken seriously by the scientific community.
A new study funded by the @NIH (Inserm), links vaccination and menstrual disorders, confirming the work carried out by @ouestmoncycle.
From the start of the vaccination campaign, many women reported these side effects.

However, this is false. In France, the ANSM, the National Medicines Safety Agency had started talking about it in July 2021. And at the time, franceinfo had already relayed women’s questions about more abundant, longer or staggered cycles. The specialists, whom we interviewed then, explained to us the link that there may be between vaccination and menstruation, since the vaccine acts on immunity, the response to an external attack against the body. But menstruation is also an immune mechanism.
For the moment, the link between the Covid-19 vaccine and menstrual disorders has not been scientifically proven, but many studies are currently emerging on the subject. The one quoted by Nicolas Dupont-Aignan, for example, was published at the end of September in the very famous medical journal British medical journal and is based on more than 19,000 testimonials. It appears that women see their periods lengthen a little, from one to three days, for one or two cycles. After that, everything is back to normal.
In any case, the European Medicines Agency is following this closely. Next month she’s going to decide whether or not to list one of those conditions, heavier periods, in what’s called the SmPC, the summary of product characteristics, of the Pfizer vaccine. In the event of menstrual disorders after an anit-Covid vaccine, he does not hesitate to consult his doctor, because a disturbed cycle can be linked to many factors such as fatigue, stress, or illness. We can also report this problem on the platform signalement.social-sante.gouv.fr.
