A student had an attack of measles and recovered from the infection. His science teacher said that he will not get that disease again in his life time. Is it true? Why?

Answer :

Yes, it because he developed immunity during the first infection of measles virus. The antibodies produced in the blood remain for a long period and kill the similar pathogens, whenever they enter the body. If the antibody production is stimulated naturally after recovering from a disease, it is called Naturally Active Acquired Immunity
