Health Experts Discover Changes In Menstrual Bleeding Among Women Following Vaccination Against COVID19

A new study that has been released on a pre-print server called medRixiv has examined patterns of menstrual bleeding in current and former menstruating women recently. The study has been based on premise that some bleeding changes might be linked to changes in clotting or inflammation that can impact the normal menstrual restore. The findings of the study have shown that COVID19 shots do affect menstrual bleeding among women. Earlier experts have denied any link between COVID19 vaccination and the menstrual cycle. They have said that there is not enough data to support a link between the two. Some health experts have linked changes in menstrual bleeding to stress. However, changes in menstrual cycles have made many people suspect that such side effects after taking COVID19 shots might lead to infertility. There has been a need to clarify these doubts as COVID19 shots have become available to adolescents. Some scientists have said that many biological mechanisms have clarified that vaccines can pose a severe immune challenge and its systemic effects on homeostasis and inflammation and restoring methods of the uterus.

Many studies and analyses have shown long-lasting disturbances in the menstrual cycle in women who have been dealing with long COVID in 2019. However, a handful of studies have examined the direct effect of COVID19 vaccines on menstrual cycles in women. Vaccines for hepatitis B, HPV, and typhoid, have been proved to be causing rapid changes in the menstrual cycle. The new study has tried to find out the range of changes in menstrual bleeding after COVID19 vaccination among regular menstruating women, the extent of breakthrough bleeding that has been reported, the possibility of finding trends of changed bleeding patterns in non-menstruating women after vaccination to understand proximate methods acting on the uterus. Experts have said that answers to these questions will help physicians in counseling patients who are hesitant to take COVID19 shots.

The study has been designed to gather data to design future studies on the link between vaccine immune response and menstrual repair mechanism. The data for the new study has been collected through surveys that have been done for six months from April to October 2021. The data that has been gathered by these surveys have been deemed as extensive snowball sampling. Overall, nearly 92529 participants have given their informed consent and have completed the survey. There have been around 39129 participants in the final sample after exclusions. Nearly 751 participants of the final sample have been given AstraZeneca vaccine, 13001 of them have received Moderna COVID19 shot, 61 of them have been given Novavax shot, 21620 of them have received Pfizer shot, 34669 of them have been given Johnson & Johnson shot and 204 participants from the final sample have been given other COVID19 shots. Experts have said that 23 participants have not been vaccinated in the final sample. In the final sample, 99.9 percent of participants have been women. Nearly 9.1 percent of participants have been gender diverse. The authors of the study have said that around 40.6 percent of participants have dealt with systemic side effects of vaccines after both doses. About 42 percent of women who have been menstruating regularly have dealt with heavier bleeding than usual. Nearly 44 percent of such women have said that they have seen no changes in their periods after taking the shots. Experts have said that 71 percent of women who have been on long-acting reversible contraceptives 39 percent of those who have been on reaffirming hormones and 66 percent of women have dealt with breakthrough bleeding post-menopause.

The findings of the new study have shown that women who are having a regular menstrual cycle are at a higher risk of having disrupted periods or heavier bleeding during their menstruation cycle after getting the shots. The authors of the study have said that people who are getting their menstrual cycles and those who have had heavier bleeding after getting the shots are more likely to be older women. These women might deal with fever and fatigue as well during their periods. Women who have had heavier bleeding during their periods might have been pregnant earlier or might have given birth recently. These women mostly belong to the Hispanic or Latinx minority group. Health experts who have been involved in the study have said that women who are prone to endometriosis, menorrhagia, and fibroids are at a higher risk of having heavier bleeding during their periods after getting the shots. Experts have said that women who are non-menstruating, premenopausal, and have dealt with heavier bleeding during their cycles after getting the shots have greater odds of having been pregnant or given birth.

On the other hand, post-menopausal women who have gone through heavier bleeding after getting COVID19 shots are more likely to be young in age and might belong to the Hispanic or Latinx ethnic group. The authors of the study have said that these effects have been seen in almost 40 percent of the participants. It has been inferred that these links are not casual but it helps in exemplifying the range of changes in menstrual bleeding after women are vaccinated with COVID19 shots. The authors of the study have made it clear that these changes in menstrual bleeding do not lead to infertility. Many other experts who have not been involved in the study have supported the findings. They have said that the findings of the study have proved that women are at risk of heavy bleeding during menstrual cycles after taking the shots. The findings can be used to understand the underlying mechanism leading to these changes in menstrual cycles after women are immunized. The study will help experts know how menstrual cycles react to severe immune and inflammatory triggers.
