Vaccination : Principle, Types and Mechanism of strengthening Immune system
Human immune system is the ability of identifying and defensing a foreign bodies and eliminating them with our bodys own healthy cells. Immune system then develops a response against antigens and this defensive response is known as immune response. During immune response, usually protein molecules such as antibodies or immunoglobulins and cell mediated cells are involved. Read more
