Why does vaccination not solve and will not be able to solve the problem of acute pneumonia?

Abstract

Vaccination is one of the revolutionary discoveries in the history of medicine, which allowed saving millions of lives. The use of vaccines can prevent the development of diseases and thereby eliminate the further need for medical care. However, achieving the desired success after applying this technique, as well as after any other medical exposure, depends on certain initial conditions. To date, it is known that optimal results were achieved after vaccination against infectious diseases that can be transmitted through contact with an already sick person, and the most striking example of such success is a complete victory over such a centuries-old scourge of humanity as smallpox [1]. At the same time, it should be recalled and clarified that such infectious processes they are the result of the presence of only one specific pathogen and the introduction of the vaccine to an individual recipient provides him with either lifelong or long-term resistance to this disease.
