Vaccinations play a major role in medicine today. Explain the
Answer
1. Phagocytosis: Cells of the immune system, such as macrophages, engulf and destroy foreign pathogens.
2. Antibody Production: Cells of the immune system produce antibodies that recognize and bind to specific pathogens, marking them for destruction.
Vaccinations work by introducing a weakened or killed form of a pathogen into the body, which stimulates the immune system to produce antibodies against it. This helps the body to recognize and fight the pathogen if it is encountered again, providing immunity against the disease.
