Answer» Solution :Our body produces the T-lymphocytes against the antigen i.e., Chickunguinea causing agent and they attack and destroy the antigen. Some of the T-cells get differentiated into memory T-cells. These cells are STORED in the lymph nodes and spleen. They recognise and produce antibodies when the same attack the body a second time. This is a very rapid PROCESS. Memory T-cells have a LONG LIFE. These cells are responsible for the life long immunity to certain diseases LIKE Chikunguinea.
