Grannyrose There is more than one job in the world, they could even stay in the same industry, providing they do not have patient/resident contact. No one is being deprived of a job. Just told that a job they had done was no longer available to someone without the vaccination.
There are all sorts of circumstances where people are restricted from following certain careers. Some professions require high standards of eyesight, teachers, doctors, nurses, police officers, all have to meet certain standards and can be barred from their profession. I think there are jobs where not having a tetanus jab and refusing to get one, could stop you joining a profession.
DH worked offshore at one point, they were not allowed offhsore for any time without an uptodate certificate of dental health and had to have regular medical checks.
The list of those whose job prospects on one career or another are too numerous to list.
