Your son should be expelled from school, becuase he could have a disease in him that is trasnferable and in that case deadly. At my college you arent aloud to live in the dorms unless you have all of your immunization records kept up to date and completed. They give the shots for a reason. Not only could he be endangering himself, but all the other teachers and children in that school. It's a long shit, i will admit, but it COULD happen and the school doesnt want to take that chance. You were unprepared and now your paying for it, don't blame them becuase you dont have everything you need together
