The entire world is packed with pathogens which we have to struggle off to leave a normal life. Due to this, we've an disease fighting capability that helps us combat off and prevent/control subsequent microbe infections. Our disease fighting capability can be categorized into two, the innate and received immune replies. The innate immune response is broadly specific and provides the first protective action against any infection. Their reaction to any subsequent illness stays exactly like the initial an infection. On the other hand, the acquired immune system response is highly specific such that it provides defence by making antibodies specific with an antigen. There is also the capability of keeping disease memory such that you will see a more powerful response to future attacks.
