[Parental refusal to mandatory vaccination in Chile. Ethical and legal challenges]

This article is an ethical and legal reflection about the current trend of parents to refuse vaccination of their children under a legal regime that establishes mandatory use of certain vaccines. We analyze the main arguments used by parents to refuse obligatory vaccination, i.e., the fear of the negative effects that vaccination may have on the child; the violation of the "right to autonomy"; religious or pseudo-philosophical beliefs; and the resistance to the State intervention in personal or family mat ters. Therefore, this statement implies a necessary ethical analysis of childhood vaccination. Finally, it will be discussed the responsibility of parents and the State -the health authority- in the care of mi nors. Vaccination is a benefit for both the inoculated and the community, the best preventive policy. At the same time, it is considered a complex case that demands a profound debate, whose purpose should be the transition from an apparent conflict between parents and the State, to convergence for the care of minors. In other words, it is emphasized the fact that parents, beyond the fulfillment of a heterogeneous normative duty, must act motivated by voluntary adherence to the best interest of the child and the community.
