Fist of all we should be clear that NO vaccine provides ANY immunity. Immunity is a natural process that requires the interaction between your natural immune system and your acquired immune system. Immunity can only be acquired by contracting the NATURAL or wild disease. "Vaccination only effects antibodies in your acquired immune system and is INCAPABLE of providing immunity.
The CDC has once again lied to us by changing the definition of "immunity". The CDC says "immunity" is the production of antibodies. The production of antibodies has NEVER been shown to prevent or mitigate disease.
You can go to the CDC site to find out how long they say each "vaccine" "protects" or provides "immunity" or how long the production of antibodies to a certain level persists. This information seems to be difficult to find. I wonder why?
The existence of "booster shots" is an admission that antibody production is transient; just as one might expect from any artificial operation on the human body.
Your definition of immunity is bizarre and incorrect. Antibodies provide immunity. Your assertions have no basis in science.
Your idea that "natural" infection provides lifelong immunity is also incorrect. Antibodies/immunity fade both for wild-type infection and vaccination.
