What are the two main types of immunity acquired from vaccines?

• A. Active immunity and natural immunity
• B. Passive immunity and adaptive immunity
• C. Active immunity and passive immunity
• D. Temporary immunity and permanent immunity

Answer: (C)

Active immunity and passive immunity are indeed the two main types of immunity that can be acquired from vaccines. Active immunity occurs when the immune system is stimulated to produce its own antibodies in response to an infection or vaccination. This process typically involves the introduction of a weakened or inactivated pathogen or its components, prompting the body to recognize it as a foreign invader and mount a defensive response. The advantage of active immunity is that it provides long-lasting protection, sometimes for years or even a lifetime, as the immune system creates a memory of the pathogen. Passive immunity, on the other hand, involves the transfer of antibodies from one individual to another. This can occur naturally, such as when a mother passes antibodies to her baby through breast milk, or artificially through injections of antibody-containing serum. Passive immunity provides immediate protection, but it is temporary, as the introduced antibodies are eventually broken down by the recipient’s body and not replaced by their own immune response. Both types of immunity play crucial roles in our overall immune defense, especially in the context of vaccinations, which are designed to enhance active immunity while sometimes also providing temporary passive immunity through antiserum in certain medical conditions. Understanding this distinction is vital for comprehending how vaccines function and the level of protection they offer
