Childhood immunizations have been controversial for centuries. To many, the idea that protection or immunity can be gained by deliberate exposure to a disease is counter-intuitive. That unease, coupled with the possibility that a child might have an allergic reaction to a vaccine’s ingredients, is enough to cause many parents to question the wisdom of inoculation.
Anti-vaccination sentiment began early, even prior to Dr. Edward Jenner’s creation of the first smallpox vaccine in 1796. In Boston in 1721, Reverend Edmund Massey published a paper titled “The Dangerous and Sinful Practice of Inoculation,” which argued that diseases were sent by God to punish evildoers and that attempts to prevent them, therefore, were sinful.
