Doctors also ignore women. So basically all of these demographics that are hesitant about the vaccine have a history of being abused by the medical community.
Yeah, like pregnancy effects being understudied, I think it's probably part of it, but even though I described the poll results as "shocking" there are a lot of complex factors at play which are manifesting here.
Flu shot uptake in the USA has hovered around 40%. Intended COVID uptake doesn't seem to be much more significant, but the various disinformation campaigns at play are actively reducing the number of people who are willing to take the vaccine in real time, if polling is to be believed.

"A poll from the Pew Research Center published in September found a significant decline from May to September in people who said they would get the vaccine if it were immediately available."
Johnson and a team of researchers published a paper in Nature in May that suggested the anti-vaccination movement bore a big responsibility for such hesitancy. It showed that although membership in online anti-vaccination groups was smaller than in pro-vaccination groups, there were more of them, their messages were more diverse, emotive and often persuading, and they were better at spreading those messages outside their groups, meaning they were able to reach more people.
Research from a forthcoming paper from Johnson and his team, currently in review for publication, shows members of communities previously considered unrelated or "undecided" on vaccines — groups for pet lovers, parent school groups, yoga fans and foodies, for instance — are increasingly connecting with the anti-vaccination movement.
The politicization of the virus, social media, the historical factors that you describe, a lack of good messaging, etc... all of this plays into this.
Also, from what I 've seen in the last ~15 years or so the anti-vaccine movement actually grew out of predominantly white women as an outcropping of the autism awareness movement... largely from white, educated women who were acting not out of their own mistreatment at the hands of doctors, but instead out of frustration from how doctors were treating their children.
