So that’s why we use vaccines. All of your vaccines are used as an agent that will build up our immune systems to fight off something that is causing us to become ill. Vaccines improve economic growth, life expectancy, protect people from spreading or acquiring the disease, and vaccines can save a ton of lives. To start off, vaccines trigger our immune systems to be able to build up our immunity to fight off a particular germ that is infecting us. An article I found states that it mimics what would actually happen. Vaccines do not keep pathogens from entering our bodies; they just prep our immune systems to be ready to block these pathogens from making us sick and unhealthy. Vaccination “programs” the immune system in a way that it remembers a particular disease or bacteria by allowing it to practice on a weaker version or killed version of the pathogen. This is called primary response. When a pathogen invades with full immunity and means the immune system has to respond quickly with specific defense this is called secondary response. A vaccine contains a germ that has been killed or has a weakened part of a germ that is responsible for an infection. Since the germ has been killed or weakened it will not cause a person to get sick. It causes us to produce antibodies. The antibodies are
