Have you ever gotten vaccinated for the rubeola virus or measles?
No I have not been vacinated for measles along with five other people in this dorm. If I were to be infected with measles how would it enter?
Measles is spread through the air in coughed-out aerosolized droplets which then are inhaled. As a result, the first body part the virus comes in contact with are the lungs.
Interesting, however, despite not having the vaccine I do have nonspecific immunity.
Yes you do have nonspecific immunity but specific immunity would prevent you from contacting a particular disease again.
I don't have specified immunity from whatever illness I have. My symptoms are a mild fever, a persistent cough, runny nose, inflamed eyes, a sore throat, and a skin rash. Four other people in this dorm have these symptoms as well.
I am a measles virus. I am currently living in my hosts mucus in the nose and throat and as a result I am causing all of these horrible symptoms as well as inflammation. There is a humoral response happening due to activation by the Helper T Cells and this response involves the transformation of B cells into plasma cells that produce and secrete antibodies to me.
A cell-mediated response is also happening due to the Helper T cells which involves the activation of phagocytes, antigen-specific cytotoxic T lymphocytes, and cytoskines in responses to an antigen. In general the cell mediated response involves eating and killing cells that are infected with the virus.
I am a natural killed cell which destroys another cell without prior exposure to it. If the body had prior exposure to the antigen then Memory B cells would provide for a more robust immune response.
We have destroyed all invading organisms. Supressor T Cells will now close down the immune response and signal the immune system to cease destruction of other cells.
