marking a stunning annexation of political messaging

Which you were told was coming the moment you started forcing people to undergo an experimental treatment in what is, if not violation of the nuremberg code, REAL FUCKING CLOSE TO ONE. Now you can't say 'my body, my choice' without reminding everyone that you didn't want to extend the same bodily autonomy to others.

It's a really savy co-option of reproductive rights and the movement's framing of the issue

It's not 'really savvy' at all. It was glaringly obvious. Over a year ago, twitter randos were openly warning you that trying to force the vax on people would obliterate the notion of 'my body, my choice', because it is literally taking decision about someone's own body away from them.

You were warned, if you bully people into vaccines they don't want, don't expect your hyperliberal abortion rights to stick around after the pandemic.

framing the decision to vaccinate as a singularly personal one also obscures its public health consequences

There are a minimum of three people directly involved in a pregnancy. The child cannot speak, and for some reason that is completely beyond me, the father has no say in anything whatsoever, giving all decisionmaking to the mother, and the invisible parent, the state.

stopping the spread of a disease to those who can't protect themselves.

Yeah, such as babies in the womb.
