Immunization (1955, Second edition)

The film explains the process of how the immune system fights infections, particularly in children. It describes how antibodies are produced in response to germs, leading to active immunity when the body develops its own defenses. It also discusses vaccination as a safer method to achieve immunity, detailing three types of vaccines: those derived from live viruses (like smallpox), inactivated germs (like pneumonia), and toxoids (like diphtheria). The film emphasizes the importance of vaccination in controlling infectious diseases and highlights the role of scientists and commercial laboratories in vaccine production.
