Half the participants in the COVID shot trials were women, but even so, scientists neglected to include questions about the women’s menstrual cycles. Therefore, when women started reporting menstrual problems after the shots were offered to the public, science had no data to back up their claims.
Alison Edelman, professor of obstetrics and gynecology at Oregon Health and Science University, told NBC News, “ Because we had no data and people weren’t paying attention to it, individuals reporting it just got blown off.”
While other vaccines have shown similar side effects, no one thought to include the possibility with this one.
