I was required to take the polio vaccine. When a baby is born it is required to have mumps, measles and rubella vaccine....and hepatitis B....
So what’s the big deal? If you don’t want your child in pubic school then don’t put him there, and don’t get the shot.
The big deal is 1: the last time a version of this particular vaccine was forced, it killed more people than the flu, and B: the mild symptoms make vaccination HARDLY a vital necessity, unlike much more serious conditions, which DO require vaccination, like small pox, polio and rubella, which your kid CAN get (and suffer from for the rest of their lives) whether they're homeschooled or not.
