Legal regulation, whether we want it or not, plays a role in protecting and promoting individual and public health. This also applies to legislation involving vaccination, especially compulsory vaccination. It is appropriate that legislation should not create barriers to the provision of health care. Where there is legal ambiguity, problems can arise that make the provision of health care more difficult, as we have seen, for example, in the context of the COVID pandemic. Furthermore, in the case of compulsory vaccination, there is a conflict between fundamental rights and freedoms. On the one hand, the right to the protection of personal freedom and bodily integrity, and on the other, the right to life and health. Most compulsory vaccinations concern children. As far as adult vaccination is concerned, this mainly includes compulsory vaccination of medical and social staff caring for patients and operating at biological risk, as well as patient groups also at risk of serious infectious disease. For these reasons, it is essential that the legislation is such that it does not impose a burden where it is not necessary and, on the contrary, allows for optimal protection of persons at biological risk.
