The harm done to children from not getting vaccinated is exponentially greater than the harm—both physical and moral—of using the vaccines. Because of herd immunity, the choice to vaccinate our children protects those who cannot receive certain vaccinations due to allergies, ages, or a weakened immune system. We must always consider whether we are using our religious liberty or concern for parental rights as cover for a choice that may cause significant harm to the neighbors we are commanded to love (Matt. 22:36-40).
