"One of the facts of this case concerns whether we should identify the right not to violate one’s own conscience with the demand for an exemption to a duly established public policy. One might easily argue that these two are not the same. Parents who refuse to vaccinate their children are not compelled to act contrary to their conscience under the law. If they are refused an exemption under some established public policy, then they will suffer the consequences of their refusal. Their children will not be permitted to enter into the local school system or some other public facility. This not a violation of conscience, but is a denial of an exemption. The case is not comparable to that of a Catholic health-care facility which is obliged by the state to dispense contraceptives because there is no compulsion to vaccinate one’s children. If one wants to appeal to conscience in order to justify a decision not to vaccinate one’s children, then the freedom not to violate one’s own conscience is all that can rightly be expected by the parent. The further claim that the exercise of conscience demands that the state must cede to the wishes of the parent for an exemption does not follow—at least, not as the right of conscience is understood by the Catholic Church."
