Now, let's begin by discussing how the natural process of infection takes place and what our body does to fight off that infection. So let's suppose we have a cut in our skin and the pathogen makes their way into our body. What happens is infection begins. And as soon as infection begins, the innate immunity of our immune system kicks in and it begins the process of inflammation. Now, what inflammation does is it ultimately aims to block off that infection to localize that infection to a specific location in our body and that prevents that infection, the pathogen, from actually spreading to other parts of our body. Now, at the same time that inflammation is taking place the adaptive immunity of our immune system begins to mobilize.
