“Cell-mediated immunity entails the system of white blood cells that attack if you unfortunately pick up a virus. And because you’ve never encountered this virus before, the virus will infect, or get inside, different bodily cells. For instance, it will infect the cells of your respiratory tract. Now your white blood cells attack these infected cells and kill them. This whole process releases substances called cytokines, which produce the ill effects you feel when you get sick.
What we call being sick—fever, flu, mucus, cough, rash, etcetera is because of our cell-mediated immune system. The virus does not create the symptoms you experience; they are compliments of your immune system. This is demonstrated clearly when you suppress somebody’s cell-mediated immune system with steroid drugs like prednisone and then infect them with a virus. They don’t get ‘sick.’ They might even die from the infection, but they won’t get what we normally refer to as sick.
On the other hand, if you give somebody the chemicals (cytokines, etc.) of their cell-mediated system, you can stimulate a cell-mediated immune response without any infection at all—no virus, no bacteria, no nothing. You merely stimulate their cell-mediated immune system and they get sick. They have a cough, fever, rash and mucus and all the rest. So that which we call being sick is a cell-mediated response.
You may not want to go around boasting how you never get sick. This is very likely because your cell-mediated immunity is repressed so that you don’t release cytokines and then suffer with colds and flus. However, this doesn’t mean that you don’t have these viruses in your body causing harm. It just means your immune system and body are too depleted, overwhelmed and tired to respond.
This is exactly what is happening when individuals receive too many vaccinations, which at some point represses their cell-mediated immunity and their body’s ability to respond to new invaders. They then become susceptible to countless diseases.”
