Write a note on Vaccination.

  1. Vaccination, administering a vaccine for protection against pathogens, is vital for primary prevention.
  2. The immune system, while naturally defending against infections, can be overwhelmed by certain pathogens, leading to severe illness.
  3. Vaccination involves exposing the immune system to a safe antigenic preparation to recognize and eliminate pathogens in future encounters.
  4. Diseases like measles, polio, tetanus, and whooping cough have been effectively controlled through vaccination.
  5. Different forms of vaccines, including proteins or sugars, dead or inactivated pathogens, toxoids, or weakened pathogens, are used to stimulate the immune response.
  6. The adaptive immune response developed through vaccination equips the body to fight off actual infections.
  7. Herd immunity is a crucial benefit, as more vaccinated individuals enhance societal defense against diseases.
  8. Vaccination contributes to the memory of specific antigens, ensuring a faster response to future pathogen encounters.
