the truth about heavy menstrual bleeding after getting covid vaccines

The Spanish Agency for Medicines and Health Products (AEMPS) has deemed it appropriate to publish a report that analyzes The impact of mRNA vaccines (Pfizer and Moderna) against covid on the abundance of menstrual bleeding, a spectacular phenomenon in itself, which when it occurs unexpectedly and close to an unusual episode such as a vaccination can create logical concern among women that have undergone this immunization process.

After the data offered by the corresponding clinical trials, in addition to those extracted from the Spontaneous reporting programs for adverse events after vaccination and those from the medical literature. The European Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicines Agency (EMA) has concluded that there is a reasonable possibility that the occurrence of heavy menstrual bleeding is related to the administration of these mRNA vaccines.

The impact on fertility and reproduction

The alarm related to this event is not exactly focused on the greatest bleeding, since it has been proven that They are transitory episodes and without a specific frequency of appearance. The biggest concern, related to the impact on fertility and reproduction, has not registered any evidence. Also, The PRAC continues to consider the balance between benefit and risk of both vaccines to be positive.

Menstrual absence or duration of the menstrual cycle after the covid vaccine

Until last October 9, 921 notifications of this disorder were registered in Spain after the administration of Pfizer and 299 notifications with Moderna in women between the ages of 12 and 49, with 15.6 million doses of the first and 6.2 million of the second in that same segment of the population. The possible relationship between these vaccines and the absence of menstruation (amenorrhea) was also studied, without finding evidence of a relationship between the two events. The magazine ‘Science’ echoed other studies, carried out both in the United States and in Norway, which spoke of cases of a slight increase in the length of the menstrual cycle after anticovid vaccination; however, these are occasional episodes that disappear after two cycles.
