Proposition de loi modifiant l'arrêté royal du 26 octobre 1966 rendant obligatoire la vaccination antipoliomyélitique.

This is a proposed law in the Belgian Chamber of Representatives that would amend a 1966 royal decree making polio vaccination compulsory. The decree sets the legal framework for the polio vaccine requirement, so changing it affects how that public health obligation applies. Based on the title alone, the bill's specific changes are not clear. The change would apply to people subject to the polio vaccination requirement in Belgium, including children and the health professionals and authorities that administer or enforce it. The metadata does not show the exact changes, so the full text would be needed to confirm who would be affected and how.
