Mandating a vaccine for a disease that a vast majority of teachers & students have a greater than 99.8% chance of surviving if contracted with the disease to accommodate the “majority” of the population who have been vaccinated, and decrease their already nearly 0% risk, is not only unconstitutional, but nonsensical. If the vaccine is so effective, the vaccinated have nothing to worry about from those who are not vaccinated. 
I trust my God-made immune system over Faucci made vaccine. Any day. Especially against a 99.8% non threatening disease. Are you kidding me?
