Which type of immunity is acquired through vaccination?

• A. Passive immunity
• B. Natural immunity
• C. Active immunity
• D. Synthetic immunity

Answer: (C)

The type of immunity acquired through vaccination is active immunity. This immunity is developed when the immune system is stimulated to produce its own antibodies in response to a specific antigen present in the vaccine. Vaccines contain either weakened or inactivated parts of a germ or the germ itself, which prompts the body to recognize it as a threat and begin producing antibodies and memory cells. This process leads to long-lasting protection against that particular pathogen, as the body is equipped to respond more effectively upon future exposure. Active immunity differs from passive immunity, where antibodies are transferred from one individual to another, providing temporary protection. Natural immunity arises from being exposed to a disease and the body developing defenses against it. Synthetic immunity, although not a commonly used term in this context, could refer to artificially creating immunity through methods that might not involve natural infection or traditional vaccination. In summary, vaccination leads to active immunity by fostering the body’s own antibody production, which provides lasting protection.
