Dr Victoria Male recently decided to conduct a large survey of women to reassure them about menstrual disturbances after the administration of a vaccine against Covid-19. It encourages such research so that experts can build on solid evidence against misinformation about the vaccine.
Dr Victoria Male, renowned immunologist specializing in fertility issues at Imperial College London, is urging the BMJ to have a broad investigation into rule changes following administration of the vaccine. In some cases, there are heavier periods than usual, delayed periods and unexpected bleeding.
The expert explains that this type of change can be caused by many factors and that a limited number of women are affected. She adds that there is no evidence that these changes have any impact on pregnancy or fertility.
Fight against disinformation
To counter these misconceptions, Victoria badly wished for solid research: “The reluctance of young women to get vaccinated is largely driven by false claims that Covid-19 vaccines could harm their chances of future pregnancy. Failure to thoroughly investigate reports of menstrual changes after vaccination may fuel these fears. If a link between vaccination and menstrual changes is confirmed, this information will allow people to plan for potentially altered cycles. ”
At present, experts do not yet understand why the vaccine would have an impact on menstruation. This may be related to changes in the immune system, boosted by the vaccine, which affects hormones and, therefore, the menstrual cycle. It can also be caused by immune cells acting differently in the lining of the uterus. However, scientists agree that a woman’s ability to have a baby is not affected by the vaccine.
