Q: What is the primary mechanism by which vaccines provide immunity?

Solution: Vaccines stimulate the immune response by introducing antigens, which prepare the immune system to recognize and fight the actual pathogen.

Steps: 6

Step 1: A vaccine is given to a person, usually through an injection.
Step 2: The vaccine contains weakened or inactive parts of a germ (antigens) that cause disease.
Step 3: The immune system recognizes these antigens as foreign invaders.
Step 4: The immune system responds by creating specific proteins called antibodies to fight the antigens.
Step 5: The immune system also creates memory cells that remember how to recognize and fight the germ in the future.
Step 6: If the person is later exposed to the actual germ, their immune system can quickly recognize and attack it.
