Question

Quintessence Classes · Accepted Answer

The correct answer is 1 and 2 only. • Statement 1 (Correct): Malaria is indeed a life-threatening blood disease caused by Plasmodium parasites, which are single-celled microorganisms known as Protozoa. It specifically targets the red blood cells of the host. • Statement 2 (Correct): The disease is transmitted to humans through the bite of an infected female Anopheles mosquito. This mosquito acts as a vector, carrying the parasite from one person to another. • Statement 3 (Incorrect): While the R21/Matrix-M vaccine is a significant breakthrough, it was not the first to achieve WHO prequalification. The RTS,S/AS01 (Mosquirix) vaccine was the first malaria vaccine to receive WHO recommendation (2021) and prequalification (2022). The R21 vaccine is the second such vaccine to be recommended. • Since statements 1 and 2 are scientifically accurate and statement 3 contains a factual error regarding the "first" status, only the first two are correct.
