Studying menstrual disturbances post COVID-19 vaccination
- Recently Instances of excessive or unexpected menstrual bleeding after COVID-19 inoculation were investigated.
Observations from the study
- 42% of people with regular menstrual cycles bleed more heavily than usual.
- 44% reported no change after being vaccinated.
- Respondents who do not menstruate reported breakthrough bleeding.
- Increased/breakthrough bleeding was associated with age, systemic vaccine side effects, history of pregnancy or birth, and ethnicity.
Negligence by many
- Typical vaccine trial protocols do not monitor major adverse events for more than seven days.
- Follow-up communications do not inquire about menstrual cycles or bleeding.
- Manufacturers didn’t address the extent to which this observation was coincidence or side effect of the vaccines.
- Medical doctors and public health experts denied any relationship between vaccine administration and menstrual changes.
International Journal of Women’s Health - Its findings
- 66.3% of women experienced menstrual abnormalities after vaccination.
- 30.5%: Symptoms appeared after a week
- 86.8%: Within a month
- 93.6%: symptoms within two months.
- Majority (46.7%) had symptoms after the first dose
- 32.4% after second dose
- 20.9% after both doses.
- Type of vaccine didn’t make a difference.
No harm to long-term fertility
- Uterine reproductive system is flexible and adaptable to stress to weather short-term challenges that leaves long-term fertility intact.
- Less severe, short-term stressors can influence menstrual cycling and menstruation.
- Speed and coverage of current COVID-19 pandemic and vaccination campaign may have highlighted under-recognised side effect of especially immunogenic vaccines administered in adulthood.
