Thanks to advances in vaccine medicine, we live in a world where our immune systems can be taught to fight off a disease before we fall ill. As adults age, however, their immune systems begin to weaken, limiting the response to infectious bacteria and viruses in their bodies.

DTaP is a vaccine given to infants and young children and is administered in 5 separate shots. Licensed in 2005, the CDC estimates that these vaccines will prevent 732,000 deaths of children born between 1994 and 2013. The vaccination protects against Diphtheria, Tetanus, and Pertussis.
