Question
How does the human body respond when vaccine is introduced into it?
Solution
In vaccination, a preparation of antigenic proteins of pathogen or inactivated / or weekened pathogen (vaccine) are introduced into the body. The antibodies produced in the body against these antigens would neutralise the pathogenic agents during actual infection. The vaccines also generate memory – B and T-cells that recognise the pathogen quickly on subsequent exposure and overwhelm the invaders with a massive production of antibodies.
