There's nothing gray about it. If we wanted States or individuals to be able to effectively nullify any cons utional right, we would have done so a long time ago, and we wouldn't need things like Cons utional amendments, the framework where you do those type of things.
The only inference you can make from that ruling is that the court doesn't consider the right of women to terminate pregnancy early a Cons utionally-protected right, despite that it is.
You can easily make the argument that this vaccination mandate might go one way or the other (though, based on precedent alone, it's unlikely States would prevail), but the abortion case is pretty egregious.
