The most ambitious study to date shows that 42% of women had a stronger period after the covid vaccine

42% of the women surveyed suffered more abundant bleeding during their period after inoculating themselves with the Covid vaccine. The pioneering study by two American researchers who set out to find out if there was a relationship between the vaccine and the menstrual disturbances reported by many women has just made its results public. Of the more than 39,000 women who responded to the survey, 42% experienced an increase in menstrual flow. The study has also found other menstrual changes linked to vaccination.

These alterations are spontaneous bleeding in the case of women who no longer had their period because they were in menopause or taking contraceptives, and also in non-menstruating people (the study included gender diversity) who were taking hormonal treatments. The researchers assure that the alterations described are temporary and point out some factors that have influenced their appearance: age, suffering from secondary effects of the vaccine such as fever or fatigue, history of pregnancies and childbirth, or ethnicity, among others.

Just over a year after many women around the world reported their menstrual disturbances after being vaccinated with the Covid serum, the study confirms the high prevalence of these incidences. Then, several investigations were launched, like this one by the North American scientists Lee and Clancy. They themselves had suffered this phenomenon and launched the first observational study on the matter.

They were followed by other researchers, such as the Physiology professor at the University of Extremadura (UEx) Ana Beatriz Rodríguez Moratinos and the postdoctoral researcher Cristina Carrasco, who belong to the Neuroimmunophysiology and Chrononutrition group of the UEx. Both are co-authors of a similar study in Spain, one of the countries with the highest population vaccination rates, which will be published in the coming months and whose preliminary results were reported by elDiario.es.

The Spanish researchers consider that the results of the study by the North American scientists serve to “shed light” on a phenomenon “initially reviled by society in general”. “As the authors themselves indicate, and given the limited previous data available, this and other vaccines have not been considered a stressor with a potential impact on the menstrual cycle, which once again highlights the constant and consequent forgetfulness lack of knowledge that we continue to have about an aspect of vital importance in women’s health”, explain Rodríguez Moratinos and Carrasco.

Although the researchers explain that menstrual disorders are not infrequent and are not usually dangerous either, the evidence provided by this study and those that are about to be published will allow us to continue investigating the mechanisms that underlie this phenomenon. And they add: “From our point of view, in no case should such research feed anti-vaccine theories, but rather serve to confirm the need for this and other side effects not to be overlooked again in clinical trials. Likewise, such evidence will provide health professionals with a greater capacity to assess their patients through information validated by science”.
