Chickenpox Lawsuit

Recently a Kentucky srtudent sued his school for limiting his extracurricular activities and banned him from school for not having his chickenpox vaccine.  This article by CNN outlines the issue further.  Apparently there was a chickenpox outbreak affecting over 32 students at the school, something that the school took serious actions towards.  This specific student is forced to miss the last of his senior year basketball season.

What should the process be with vaccines in schools?  Should students be suspended because they do not have vaccines? Is it fair to ban this student from extracurriculars that he is passionate about? I am interested to hear your thoughts.
