COVID vaccine recipients report changes in menstrual bleeding - study

A study found that 42% of respondents reported heavier bleeding than usual during their menstrual cycles after being inoculated with the COVID-19 vaccine.

In this study, which was published in the peer-reviewed scientific journal Science Advances, researchers surveyed nearly 40,000 women who had received their COVID vaccine schedule and found that 42% reported heavier bleeding than usual within the first three months after being vaccinated.

While 44% of respondents reported no changes, there were also changes reported among women who do not menstruate – 71% of people on long-acting reversible contraceptives, 39% of people on gender-affirming hormones, and 66% of postmenopausal women reported breakthrough bleeding.

Menstrual activity and vaccines The COVID vaccine is not the first to result in irregular menstrual cycles for those inoculated – a 1913 study cited in the research found that the typhoid vaccine was associated with menstrual irregularities – including irregular menstruation, discomfort; and heavy bleeding in more than half of the female sample studied. Hepatitis B and HPV (human papillomavirus) vaccines also resulted in irregular menstrual cycles.
