I'm afraid religioun just might be the only way to avoid vaccines (in some states and/or cases). My understanding that the laws are becoming so 'tight' and the loopholes so few...that pleading 'religious freedom' is about the only way to get your child a public education without having them injected with government mandated vaccines.
In Iowa (where we live) there are a couple of other alternatives other than the religion thing (if I'm remembering correctly), but if it comes down to a state or federal "emergency" then the government has the right to vaccinate anybody and everybody by FORCE.
'Tis another battle to be fought and another victory to be gained (and another FREEDOM to be restored...even though many people have/had no idea they'd lost their freedom).
