Imagine an outbreak, one of the most infectious viruses that thrives most in adolescents or infants, lets say the measles, happens in your hometown. Presumably, you and your family are all safe, for you have all been immunized. But your neighbor’s child (for now, lets say Tim) has yet to get vaccinated, and his parents refuse. Tim’s parents have strict moral values, which infringe on his ability to get the medication he genuinely needs. They believe vaccinations cause autism, vaccines do more harm than good, and by not immunizing, their kids build up a stronger immunity.
