Halachic aspects of vaccination

Abstract

Perhaps it is because we live in twenty-first century America, a country largely immune from true epidemics, that we take vaccination for granted and some parents even consider not vaccinating their children. A Jew living in the eighteenth century would have longed for respite from the relentless onslaught of diseases, and could only have dreamed of having a way to prevent them. The thought of refusing vaccinations would never have entered his mind. Unfortunately, nowadays, as a result of misleading information, some parents are confused about the issue and do not realize the importance of vaccinations. A cursory review of the origins of vaccination in medical and rabbinical literature may provide some perspective on the issue.
