Personally, I think its just as nutty having people pressure others into taking shots into their body that there is clearly risks associated with it. Who is the self centered one here?
It's not that black and white.
I'm less interested in the employment aspect than the general issue of vaccine resistance.
Getting vaccinated isn't something you do just for yourself. You do it to help break the chain of transmission, not knowing whether the vaccine will be effective for you personally and knowing that there are medical risks to this treatment.
Getting vaccinated is not at all an assurance of immunity from COVID. Under ideal conditions, at least 5% of vaccine recipients are not immune, and any one person has no way of knowing whether they are immune or not unless they later get COVID. However, if enough people get vaccinated we will achieve herd immunity, and this is something you mainly do for the greater good.
Many people take risks and make sacrifices in urgent circumstances for the greater good. Of my mother's four brothers, two went to war in Europe and on the North Atlantic, making very great sacrifices and taking significant personal risks, all for the greater good. One was too young to fight, and the eldest stayed home in the farm, taking some derision for not contributing as was common for young, single able-bodied men of the day.
I don't find it at all surprising that persons without serious medical conditions should feel themselves under some moral season to obtain the vaccine, and personally I don't find that at all inappropriate.
