The simple answer to ANY medical procedure, pharmaceutical, or biologic should be a YES or NO.  There should not even be a need for an exemption because every sovereign human has control over what is put into his or her body.  This vaccine does not prevent the contraction or transmission of COVID19 - therefore regardless of vaccination status, people can spread the disease.  This vaccine also comes with a host of adverse reactions, side effects that for many are worse than the disease itself.  Forcing people to accept an experimental pharmaceutical in order to keep a job (teachers and staff) or participate in public schools (young people are guaranteed access to free public education paid for by their tax dollars) is criminal and screams of medical segregation.  
Anyone who has paid attention has seen that medical exemptions are impossible to obtain in states where religious and philosophical exemptions have been removed.  In many cases, a medical exemption is only available to a person who can prove an adverse event in the first dose of the series - this is forcing people to put themselves in harms way and even then a medical exemption would not be guaranteed.  Parents should not be forced to sign their child up for a medical experiment simply to be able to enroll them in public school.

WHERE THERE IS RISK; THERE MUST BE CHOICE.
