Menstrual disturbances as ‘potential signals’ after vaccination
In its latest update, published last Friday, the National Medicines Safety Agency (ANSM) placed menstrual disorders as “potential signals” after vaccination. These potential side effects concern the Pfizer (Comirnaty) and Moderna (Spikevax) vaccines. To date, the ANSM has reported 36 cases reported with the Moderna vaccine, out of more than 6.4 million injections, and 229 with the Pfizer vaccine, out of more than 53 million injections. In this sense, the ANSM announced “in its report that” the analysis of cases of menstrual disorders occurring after vaccination with Spikevax led the monitoring committee to consider that this is a potential signal which also concerns Comirnaty, whose profile is similar. This potential signal will be brought to the European level “.
At the same time and despite the fact that no causal link has yet been defined by the National Medicines Safety Agency, hundreds of testimonies are pouring into social networks about these menstrual disorders. Menstruating people thus testify to having had longer menstrual cycles, late or even heavier periods than usual.
No risk to the fertility of men and women
According to Professor Bertrand de Rochambeau, president of the national union of gynecologists and obstetricians of France (SYNGOF), these disturbances of the menstrual cycle are not ” neither serious nor dangerous “. The doctor thus recalls that ” the menstrual cycle is a variable phenomenon. It can be influenced by all kinds of external events. Stress caused by the injection or the few flu-like symptoms it can cause are potential triggers for menstrual cycle disorders “. As for Geoffroy Robin, gynecologist and President of the Medical Gynecology Commission of the CNGOF (National College of Gynecologists and Obstetricians), he explained that these side effects are related to the immune response. Besides, ” It is not the vaccine directly that would be the cause of a menstrual disorder but the inflammatory reaction that it would induce »He sums up.
Regarding the fertility of men and women, Inserm clarified that “ today no valid scientific evidence or theory that would suggest that the vaccine against the Covid-19 would pose a risk on the fertility of men and women “.
