I Have hundreds of studies and doctors that think otherwise ;)

University of Chicago researchers found that Memory T cells are “distressingly slow learners”, requiring “several generations” of intensive stimulation to make a lasting impression on T cells “No vaccine trial to date has been able to produce significant numbers of memory T lymphocytes...”

The Pasteur Institute found that “98% of the immune responses triggered at the early stages of infection are non specific. These non specific responses had been observed following different infections by viruses, bacteria, parasites and fungi.” This means that natural immune system affords 98% of the early response to an infectious disease agent, while the adaptive or memory-based protective response that vaccination seeks to stimulate represents only 2% of early response.
