Actually, if they did this the way they did in my county (I teach in WV), the kids were NOT given the vaccine unless their parents returned the permission form.
Chances are, if the kid was in line for a vaccine, Mom probably signed up for it. Parents have the right to make medical decisions for their kids. They do it at school because they can get them all done in a single day.
No where in the article did it say that the shots were mandatory.
Did you see this from Mass ?
Resist injections? Go to jail!
