Vaccinations

Abstract

Vaccinations are the act of exposing the body to a specific pathogen. This pathogen is presented to the body in the form of a vaccine. A vaccine is composed of a very small number of weak pathogens, and when these pathogens are then placed into the body they create memory b-cells. Memory b-cells are how the immune system fights off the virus or disease when you come in contact with it in the future. Not only do vaccinations provide protection to the individual but they also help to provide protection to the entire community by reducing the spread of disease. Vaccinations are one of the greatest achievements of biomedical science and public health. They help to reduce extremely high death rates to reductions of 99%, some have even been eliminated (Orenstein).
