Roe V. Wade set several precedents. One of these legal precedents was to uphold the right to individual bodily autonomy in medical decisions. (obviously "bodily autonomy" doesn't apply if you consider the fetus to be a separate life. But that was not the court's take)
Back to the main point: They cannot mandate the vaccine if you have a right to bodily autonomy in medical decisions.
And even without a federal law like Roe, blue states would still keep abortion legal.
So I suspect the federal government is willing to sacrifice Roe V. Wade if it means they can mandate the vaccine.
Thoughts?
I've been saying that using Roe v Wade as a basis for vaccine exemption is dumb. The case is rotten and you don't want to bring that rot into anything else.
There is decades' worth of case law using Roe v Wade that hinges upon that medical privacy thing that isn't even what the case was actually about. If it unravels, it could go any way but the leftists now hold almost all the cards.
