Childhood illnesses like measles, mumps and chicken pox produce symptoms which reflect the efforts of the immune system to clear the virus from the blood, which it does by sending it out exactly the same way it came in. When a child recovers from measles, you have true immunity.
That child will never, never again get the measles no matter how many epidemics he is exposed to. Furthermore, he will respond vigorously and dramatically to whatever infectious agents he is exposed to. The side benefit of that disease is a nonspecific immunity that charges or primes his immune system so that it can better respond to the subsequent challenges that it is going to meet in the future.
Now, by contrast, when you take an artificially attenuated measles vaccine and introduce it directly into the blood and bypass the portal of entry, there is no period of sensitization of the portal of entry tissues. There is no silent period of incubation in the lymph nodes. Furthermore, the virus itself has been artificially weakened in such a way that there is no generalized inflammatory response.
By tricking the body in this way, we have done what the entire evolution of the immune system seems to be designed to prevent. We have placed the virus directly and immediately into the blood and given it free and immediate access to the major immune organs and tissues without any obvious way of getting rid of it.
The result of this, indeed, is the production of circulating antibodies, which can be measured in the blood. But that antibody response occurs purely as an isolated technical feat, without any generalized inflammatory response or any noticeable improvement in the general health of the organism.
Quite the contrary, in fact. I believe that the price we pay for those antibodies is the persistence of virus elements in the blood for long periods of time, perhaps permanently, which in turn presupposes a systematic weakening of our ability to mount an effective response not only to measles but also to other infections. So far from producing a genuine immunity, the vaccine may act by interfering with or suppressing the immune response as a whole in much the same way as radiation and chemotherapy, corticosteroids and other anti-inflammatory drugs do.
Chronic long-term persistence of viruses and other proteins within cells of the immune system produce chronic disease. We know that live viruses are capable of surviving or remaining latent within host cells for years without continually provoking acute disease. They do this by attaching their own genetic material to the cell, and replicate along with the cell. That allows the host cell to continue its normal functioning but continuing to synthesize the viral protein.
Latent viruses produce various kinds of diseases. Because the virus is now permanently incorporated within the genetic material of the cell, the only appropriate immunological response is to make antibodies against the cell, no longer against the virus. So, immunizations promote certain types of chronic diseases. And far from providing a genuine immunity, the vaccines are actually a form of immunosuppression.
