VACCINATION • In vaccination, a preparation of antigenic proteins of pathogen or inactivated/weakened 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 kill the invaders with a massive production of antibodies. Production of large scale of vaccine become possible through DNA recombinant technology which allowed the production of antigenic polypeptide(vaccine) in bacteria and yeast. Hepatitis B vaccine is produced from yeast through DNA recombination technology for large scale immunisation.
