Which of the following diseases are controlled by immunisation?

Immunisation is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine. A vaccine consists of weak or killed pathogens and it stimulates the body's own immune system to protect the person against subsequent attacks of the disease by synthesising antibodies. Diseases like measles, rubella, polio, etc, can be prevented by immunisation. As of now there are no effective vaccines found for common cold.
