Rabat – The British Medical Journal released a recent study, which confirmed a causal link between COVID-19 vaccines and menstrual cycle disturbances.
The study, which assessed the menstrual cycle of 19,622 women around the world aged 18-45 years, revealed a variety of menstrual cycle changes following COVID-19 vaccination, including longer and shorter cycles, missed cycles, heavier and lighter menstrual flow, and intermenstrual spotting.
The research, whose goal was to highlight the consequences of the vaccine, showed that unvaccinated women had no alteration in their menstrual cycle.

The study indicated that second COVID-19 doses increased the menstrual cycle of the majority of vaccinated women, particularly when administered during the menstrual cycle.
When both COVID-19 vaccine doses were administered during the same menstrual cycle, the duration of the cycle witnessed an increase of roughly three days on average.
Researchers admitted that such changes were only temporary.
Some women also reported other unanticipated outcomes, such as a change in menstrual flow or the start of menstruation after receiving a COVID vaccine dose.
Although the study confirmed a causal link between COVID-19 vaccination and women’s menstrual cycle, the concrete link between the injection and the irregularities has not yet been explained, the study shows.
