So not all COVID-19 vaccines available in different countries have been considered. More than half of the vaccinated received the BioNTech-Pfizer vaccine (55%) 35% received Moderna, and 7% the J&J/Janssen. Women who received the AstraZeneca vaccine were not included in the study. However, the study only looked at the vaccines produced by BioNTech-Pfizer, Moderna, and Johnson & Johnson. The study monitored the six consecutive cycles after getting a jab.

Limited data on effects of COVID vaccines According to the study, the COVID-19 vaccinations assessed do not have any further effects on the period. The change was categorized as minimal and, most importantly, only temporary. If women received two vaccine doses within a single menstrual cycle, a two-day change was observed, on average. The timing of the next period changed by less than one day, on average, during the menstrual cycle when the shot was administered. The main finding is that menstruation starts about a day later after the vaccination than in women from an unvaccinated control group. Many women have observed irregularities in their menstruation cycles after getting vaccinated against COVID-19 Image: Martin Meissner/ASSOCIATED PRESS/picture alliance New study shows menstrual side effects of COVID jabsĪ study published in the journal 'Obstetrics & Gynecology' now confirms one phenomenon that some women had observed after getting their coronavirus vaccinations: a change in the length of menstrual bleeding.Īccording to the study, which collected data from nearly 4,000 users of a smartphone app that tracks menstrual cycles, vaccination against COVID-19 was linked with a small and temporary change in menstrual cycle length. By May 2021, only a small number of individuals (fewer than 200) had self-reported a menstruation-related issue. Menstrual side effects are not actively tracked in VAERS, the US-based database that allows vaccine recipients to enter possible side effects themselves. The effect of COVID-19 vaccines on menstrual cycles, like many other vaccine candidates, was not included as a possible side effect for participants during the 2020 clinical trials. Some have even said they skipped an entire cycle.

The changes observed range from earlier or later periods that are heavier or lighter, to longer or more painful periods. Many women have observed irregularities in their menstruation cycles after getting vaccinated against COVID-19. Since the rollout of the COVID-19 jabs, there have been many reports of potential side effects. While most have been ruled out through various studies, one of the most persistent claims has prompted much debate online and in the home.
