Vaccination & Immunisation
- Vaccination is a process by which specific antibodies are developed in a normal man to immune the body from specific diseases caused due to pathogens.
- A preparation of antigenic proteins of pathogen or inactivated/weakened pathogen (vaccine) is introduced into the body.
- The antibodies produced in the body against these antigens would neutralize the pathogenic agents during actual infection.
- The vaccines also generate memory – B and T-cells that recognize the pathogen quickly on subsequent exposure and overwhelm the invaders with a massive production of antibodies.
- Immunization is the process by which the body produces antibodies against vaccine-preventable diseases through the administration of specific vaccines.
- Vaccination provides immunization after a time period.
- So passive immunization is practiced in such cases where prepared antibodies, antitoxins and antivenoms are injected to the patients. Ex. Tetanus, Snake bite.
- Recombinant DNA technology has allowed the production of antigenic polypeptides of pathogens in bacteria or yeast.
- Vaccines produced using this approach allow large scale production and hence greater availability for immunisation, e.g., hepatitis B vaccine produced from yeast.
