A key feature of the immune system is its ability to recognize “self” from “non-self”. Discuss some examples of where this feature malfunctions. Compare the body’s humoral responses to its cell-mediated responses. Discuss what types of cells are used in each response, their process of action, and the final outcome of the antigen. Using the graph, draw a line to illustrate the humoral immune response when an individual is exposed to the same antigen multiple times. (NOTE: please label all antigen exposure points. For instance, the individual may first be exposed to an antigen at time 0:05, there will be an annotation at time 0:05 dictating “antigen exposure”) Explain why are vaccines so effective in stopping diseases.
