That's because it is illegal and in violation of the Nuremberg code which outlaws coerced and forced medical experimentation on people and that includes denying people an education if they don't take an experimental mRNA vaccine that's not gone through all the trials and been properly tested for safety and officially approved for official public use which this vaccine has not. This vaccine has not finished their trials and all safety concerns were waived in order to be authorized for emergency use only for anyone that wanted it and cannot be mandated for people to take by a university, employer, business nor government. Insurance will not cover injuries resulting from emergency use only experimental mRNA vaccines that rewrite your DNA. You are on your own if you take this experimental mRNA vaccine and get injured or die from it since makers of this vaccine are absolved of legal liability by the crooked government.
