The fact that you worry now because it may kill you or a loved one.....and you need someone to blame if that happens. So why allow an exemption at all for religious or medical reasons? Take the shot or be fired,no reason or excuse. You have allergy to eggs,to bad,Gullian-Barr syndrome,tough luck,religious reasons,no,you are all fired.
So what you are saying is you respect the rights of these people but not the people who just say NO,or do you agree ALL FIRED?
If the protection of people in care of the hospital are your only concern,there should be no exemptions period.
