Among the options provided, **Onchocerciasis** cannot be prevented by immunization. So, the correct answer is D. Onchocerciasis. Onchocerciasis, also known as river blindness, is a disease caused by infection with the parasitic worm Onchocerca volvulus. It is transmitted through the bites of infected blackflies and is not preventable through vaccination. The other diseases listed - Poliomyelitis, Tuberculosis, and Cholera - can all be prevented through vaccination.
