Which of the following diseases induce immunity?
Correct answer: A. Smallpox
- A. Smallpox
- B. Jaundice
- C. Diabetes
- D. None of these
Explanation
A person who recovers from smallpox develops specific immune memory against the smallpox virus, although vaccination is the safer way to acquire protection. Diabetes does not normally produce protective immunity, so students may choose it simply because it is a major disease rather than an infectious disease that stimulates immune memory.
