Final answer:
The inoculation effect works by stimulating the immune system to develop immunity against specific pathogens without experiencing an infection. Vaccines contain non-infectious antigens that trigger an immune response, resulting in the production of memory cells. These memory cells help the body recognize and respond to the pathogen if encountered in the future.
Step-by-step explanation:
The inoculation effect works by stimulating the immune system to develop immunity against specific pathogens without the individual having to experience an actual infection.
When a person receives a vaccine, non-infectious antigens derived from known pathogens are injected into the body. Along with these antigens, adjuvants are delivered to help stimulate the immune response.
The immune system recognizes the antigens as foreign and mounts an immune response, producing memory cells that remember the specific pathogens. If the person is exposed to the actual pathogen in the future, their immune system can quickly recognize and respond to it, preventing the individual from getting sick.
