**Core Concept**
Malaria is a mosquito-borne infectious disease caused by Plasmodium parasites. Protection against malaria can be achieved through various measures, including vaccination, chemoprophylaxis, and vector control.

**Why the Correct Answer is Right**
The correct answer is based on the understanding of malaria prevention strategies. Malaria can be prevented by using insecticide-treated bed nets (ITNs), indoor residual spraying (IRS), and antimalarial drugs such as chloroquine, mefloquine, and doxycycline for chemoprophylaxis. Additionally, the RTS,S vaccine, also known as Mosquirix, is a vaccine that provides partial protection against malaria.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it is not a recognized method for malaria prevention.
**Option B:** This option is incorrect as it is not a recognized method for malaria prevention.
**Option C:** This option is incorrect as it is not a recognized method for malaria prevention.

**Clinical Pearl / High-Yield Fact**
It is essential to note that no malaria vaccine provides complete protection, and chemoprophylaxis should be used under the guidance of a healthcare professional. Additionally, the use of insecticide-treated bed nets and indoor residual spraying are crucial in areas with high malaria transmission.

**Correct Answer:** D.
