But the family itself is not beyond regulation in the public interest, as against a claim of religious liberty. And neither rights of religion nor rights of parenthood are beyond limitation. Acting to guard the general interest in youth's wellbeing, the state, as parens patriae, may restrict the parent's control by requiring school attendance, regulating or prohibiting the child's labor and in many other ways. Its authority is not nullified merely because the parent grounds his claim to control the child's course of conduct on religion or conscience. Thus, he cannot claim freedom from compulsory vaccination for the child more than for himself on religious grounds. The right to practice religion freely does not include liberty to expose the community or the child to communicable disease or the latter to ill health or death. The catalogue need not be lengthened. It is sufficient to show what indeed appellant hardly disputes, that the state has a wide range of power for limiting parental freedom and authority in things affecting the child's welfare, and that this includes, to some extent, matters of conscience and religious conviction....A democratic society rests, for its continuance, upon the healthy, well rounded growth of young people into full maturity as citizens, with all that implies. It may secure this against impeding restraints and dangers within a broad range of selection. Among evils most appropriate for such action are the crippling effects of child employment, more especially in public places, and the possible harms arising from other activities subject to all the diverse influences of the street. It is too late now to doubt that legislation appropriately designed to reach such evils is within the state's police power, whether against the parent's claim to control of the child or one that religious scruples dictate contrary action.
