In Slovenia immunisation of children is mandatory by law and parents do not have the freedom to make the decisions regarding it. In Foucault’s theory compulsory immunisaton falls under the biopolitical power with elements of the disciplinary authority. This type of authority has power over all human biological processes, such as procreation, fertility and mortality, level of health, length of life, and longevity, while at the same time posessing the power of control over all the conditions, that influence these processes. This is a complete system of interventions and regulatory controls, the biopolitics of the population. This is the authority of encouragement, guidance, regulation and control, through which bodies and lives are managed. Schools, barracks, prisons, psychiatric institutions have been developed as instruments of population regulation as well as public healthcare and mandatory vaccinations, which enable subjection of bodies and population control. In western European coutries vaccination is mostly voluntary, while in Slovenia and other southern and eastern European countries immunisation is mandatory. Failure to comply with the law is a misdemeanor with the threat of a monetary fine.
