I suggest that the government or the Ministry of Health, through austerity measures such as compulsory vaccination against infectious diseases, makes self-selection and compulsory vaccination a matter of choice.
 
justification
1. an insured person who has insurance and opts for compulsory vaccination should be a self-payer, but when a disease prescribed in a compulsory vaccination occurs, the treatment should be financed by the insurance itself.
 
2.an insured person who is insured and chooses not to be vaccinated should, in the event of the onset of a disease prescribed in the compulsory vaccination and the treatment is paid for by the insured person himself.
