Children have a near statistical zero chance of dying from COVID, as a such the government is not able to seriously defend any position related to the necessity to vaccinate children. 

As far as the denial of religious exemptions, the practice of religion is a pre-governmental right, which only a tyrannical government would even ATTEMPT to take away.  The state of VA would be doing serious harm to the mental and spiritual well being of its citizen to force them to set aside their sincerely held beliefs for this vaccine.  We will not worship the man-made vaccine as the sole way out of the pandemic, and you should expect the citizenry to pursue every legal option if this mandate gets passed, which you know you will not win.
