**Core Concept:** Roll back malaria is a global initiative launched by the World Health Organization (WHO) in 2001, aiming to reduce and eventually eliminate malaria. It focuses on vector control, improved diagnosis and treatment, and research and development.

**Why the Correct Answer is Right:** Option D is wrong because the Roll back malaria program does not prioritize the development of a malaria vaccine alone as a strategy to eliminate the disease. Instead, the program emphasizes a comprehensive approach addressing vector control, diagnosis, treatment, and research.

**Why Each Wrong Option is Incorrect:**

A. Option A is incorrect because the Roll back malaria initiative does not solely focus on the development of antimalarial drugs but also addresses vector control, diagnosis, and research.

B. Option B is wrong because the Roll back malaria program does not emphasize the development of antimalarial drugs without considering vector control, diagnosis, and research.

C. Option C is incorrect because the Roll back malaria program aims to reduce and eliminate malaria through a combination of strategies, not just the development of antimalarial drugs.

**Clinical Pearl / High-Yield Fact:** The Roll back malaria initiative highlights the importance of a multifaceted approach to combat malaria, including vector control, improved diagnosis, treatment, and research, rather than focusing on a single strategy like drug development. This approach has been proven effective in reducing malaria cases globally.

**Correct Answer:** D. Development of antimalarial drugs alone is not sufficient to achieve the goal of Roll back malaria. The initiative prioritizes a comprehensive approach involving vector control, improved diagnosis, and research.
