Types of Vaccines, Vaccination and National Immunization Schedule

FATHER OF IMMUNOLOGY

Production of vaccines comes under a branch of life science called immunology. Edward Jenner is the father of immunology.

TERM – VACCINE AND VACCINATION

The term vaccine is coined from “Variolae Vaccinae” meaning “small pox of cow” and the term was devised by Edward Jenner to denote cowpox.

HOW VACCINES WORK?

The content of vaccine can be called as an agent which stimulates the body’s immune system to recognize it as a threat, then destroys it and keep a rocord of the attack so that the immune system can more easily recognize and destroy any later attack of the same disease.

Types of vaccines

Vaccines are broadly classified on the basis of content they are carrying. Sometimes it may be dead or inactive organisms or may be purified products derived from them.

1. Inactivated Vaccines – Contains inactive, but previously virulent micro organisms.

Eg. Influenz, cholera, polio, hepatitis A and Rabies

2. Attenuated – Contains live, attenuated micro organisms. These organisms closely resemble the original virulent microbes but are less dangerous.

Eg. Yellow fever, measles, rubella, mumps

3. Toxoid – Contains inactivated toxic compounds that cause illness without micro organisms.

Eg. Tetanus and Diphtheria.

4. Subunit – Contains protein subunit which can create an immune response.

Eg. Hepatitis B and HPV vaccines

5. Conjugate – Contains polysaccharide outer coats of microorganisms (bacteria) which works like protein antigen creating an immune response.

Eg. Haemophilus Influnzae Type B vaccine
