If you keep up with the various revelations coming out about the trials it isn't surprising at all. They seem to have been deeply and fundamentally flawed to the extent that nothing they told us was true. Quite possibly due to deliberate fraud, judging from some of the events (search for details of people who died or were severely injured immediately after taking the shots yet were mysteriously not recorded as such).
From the article: Individuals who took part in Covid vaccine trials were not asked if they experienced menstrual changes.
Ah, good to know that this was the input being referenced when health authorities were issuing proclamations that there was definitely 0% chance of any impact on fertility from the mRNA vaccines.
They didn't just have a broad, open-ended "did you notice anything was off?" question?
Because doctors historically give only about 60% of a shit what happens to AFAB bodies, less if that body isn't white.
