Statement (I): Vaccines provide natural acquired active immunity.
Statement (II): The latest hot spot in the field of vaccine research is the development of oral vaccines.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Vaccine immunity is artificially acquired, and current vaccine research focuses on DNA and edible vaccines.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
Immunity may be natural or artificial, and active or passive.

Step 2: Statement (I)
A vaccine deliberately gives antigens, so the immunity is artificially acquired active immunity, not natural. Statement (I) is incorrect.

Step 4: Conclusion
