If you are offered a vaccine and choose to refuse, you are making a conscious to remain a danger to people who are unable to be vaccinated in society and people who have been vaccinated and unknown to then are not effectively protected by it.
That is fine in general society because those people have the responsibility to protect themselves, are aware that people have not been vaccinated, and go about their daily lives at their own risk.
However, there are situations where people have no to defend themselves. Situations where they are forced against their will as it were. If you are in hospital after an accident, giving birth, falling in the street, if you are at school, if you are elderly and have a care worker visit, if you need to go to a doctors, or need to have someone attend your home due to disability, are stopped in the street for no reason by the police, or are approached by a security guard in a shop.
All these people have no choice. The only person in that equation that has a choice is the person who is providing in care. They are also the only person who is in a position of responsibility in those cases.
All people in a position of where they can impose themselves on others without that other person having the ability to remove themselves and protect themselves, like those outlined above, should be offered a vaccine and if they refuse they should be placed on paid leave. They should then be issued with a written warning that it has been brought to managements attention that they are actively endangering patient/children whatever and asked to remedy the endangerment of those people who are under their care. If they then refuse to they should be sacked.
You cannot sanction forcing vulnerable people into the hands of medical staff/teachers/carers who do not care about them and refuse to protect their safety. Nor can you sanction allowing people who can knowingly infect and kill the public to have the power to approach and physically restrain people.
So I say sack them all. There will be plenty of cleaning jobs in schools at night, and plenty of lorries to be loaded and orders to be picked in retail. They can work where its far harder for them to inflict damage on others.
