Vaccinations have profoundly impacted public health, preventing infectious diseases that were previously responsible for millions of deaths each year. Many of these diseases are rare in the developed world now, mostly because of vaccines, but they still cause substantial mortality in the developing world. The benefits of vaccines do not come without a price—adverse effects are a risk of incorrectly designed vaccines and some involve damage to the nervous system. These include aseptic meningitis due to an attenuated vaccine virus, full disease after inadequate inactivation of the virus, and the triggering of central or peripheral nervous system autoimmune inflammation. Many of these effects have been corrected after epidemiologic detection. |
