Vaccination Theory

Vaccination Theory is based on the idea that exposing the immune system to a harmless form or piece of a pathogen (like a virus or bacteria) trains it to recognize and fight the real, harmful version in the future. Vaccines often contain weakened or inactivated parts of the pathogen, which stimulate your immune system to create defenses—such as antibodies—without causing illness. When exposed later to the actual pathogen, your immune system can respond more quickly and effectively, providing immunity and reducing the risk of disease. This proactive approach helps protect individuals and communities from infectious diseases.
