This paper argues that childhood vaccination should be considered a necessary of life as defined in Section 215 (1) of the Canadian Criminal Code, and parents who do not vaccinate their children should be considered responsible for death by criminal negligence if their child dies from a preventable disease. It timelines the long history of the vaccine debate from the perspective of both science of skeptics and points to the since-retracted Wakefield paper as the catalyst for the re-emergence of this debate, detailing the science behind why vaccination is safe, effective, and necessary. It then outlines the theory of medical neglect as a form of indirect killing in the same way starvation or lack of shelter is currently considered neglect under the Code, to prove that vaccination is required for all children who can be vaccinated and the dangers of not doing so. It concludes with notes on disease prevention and education to increase the number of vaccinated children, as the goal of defining vaccination as a necessary of life is not meant to punish parents but to encourage higher rates of vaccination and a greater communal knowledge of medical procedures.
