Menstrual Bleeding Listed as Side Effect

The European Medicines Agency (EMA) recently published clinical data that recommended adding heavy menstrual bleeding to the list of side effects of mRNA COVID-19 vaccines.

Announced on October 28, 2022, the EMA stated heavy periods, which are bleeding characterized by increased volume and/or duration, have been observed during clinical trials, from cases in the real world, and in related medical literature.

The European regulator has now concluded that there is at least a "reasonable possibility" that heavy menstrual bleeding is causally associated with these COVID-19 vaccines, reported Natalie Glover with Reuters.
