What specific type of acquired immunity do vaccines provide:?
1. As a vaccine is a man made product, the “artificially acquired” component is obvious. The vaccine tricks the body into defending itself against a fake infection so that it will be prepared for a real one. This is a form of active immunity where the body produces its own defenses. The answer is C. 2. The non-specific chemicals are always present and act instantly to protect the body. However, they are not universally effective and the body takes time to engineer specific defenses, thus the answer is B. 3. D is not true. I do not know for sure about the rest. Scientists learned about viral HIV and AIDS in the early 1980s.
