Vaccination results in the production of antibodies which destroy toxins of germs. When a vaccine is introduced into the body, it triggers an immune response, causing the immune system to produce specific antibodies against the pathogen. These antibodies circulate in the body and are ready to attack the pathogen if it enters the body. In this way, the body is able to quickly and effectively fight off the pathogen and prevent the development of the disease. This is the primary mechanism by which vaccination protects against infectious diseases.
