Unnecessary Vaccination

Vaccination is taught in medical schools as fact rather than theory, meaning that it is seen as having been proven safe and effective. Yet the immunity theory on which the practice of vaccination has been built is still considered a hypothesis, not a fact. Meanwhile, we tend to accept anything that is not necessarily established and popular as being true, but this the case. Long-term and widespread usage does not prove anything other than human being's faith in and devotion to the practice in question.
