IMMUNITY HISTORY AND CLASSIFICATION

The prehistoric view of disease was that due to theurgic punishment for bad deeds,evil thoughts etc. Hippocrates thought alteration or imbalance in one among the three (blood, phlegm & bile). Also popular during this point before learning that communicable diseases came from germs/microbes was the miasma theory, which held that diseases like cholera or the Black Death were caused by miasma, a noxious sort of “bad air.

With Louis Pasteur’s scientific theory of disease, that science of immunology began to elucidate how bacteria caused disease, and how, following infection, the physical body gained the power to resist further infections. In 1798, Jenner introduced the far safer method of deliberate infection with cowpox virus, (smallpox vaccine), which caused a light infection that also induced immunity to smallpox. By 1800 the procedure was mentioned as vaccination. To The success and general acceptance of Jenner’s procedure would later drive the overall nature of vaccination developed by Pasteur et al. towards the top of the 19th century In 1891, Pasteur widened the definition of the vaccine in honor of Jenner and it then became essential to qualify the term, by pertaining to the polio vaccine, measles vaccine, etc. first clinical description of immunity which arose from a specific disease-causing organism is probably A Treatise on Smallpox and Measles 1848 in the 9th century describes the clinical presentation of smallpox and measles and goes on to point that exposure to those specific agents confers lasting immunity The first scientist who developed a full theory of immunity was Ilya Mechnikov after he revealed phagocytosis in 1882.

Immunity refers to the ability of the human body to resist diseases caused by microorganisms. IMMUNE BOOSTERS SUPPORT THE PROCESS. Immunity may be a complex human system that has the capacity to acknowledge and tolerate whatever belongs to the self and to acknowledge and reject what’s foreign (non-self).

Immunity is mainly classified as follows:

INNATE IMMUNITY: Everybody is born with natural active immunity to prevent any infection in a normal healthy situation.

ADAPTIVE IMMUNITY: When any antigen (toxins released by disease-causing organisms) enters the body antibodies are created in the body naturally to fight against (inactivate) such antigens thereby prevents infection.

IMMUNE BOOSTER SUPPLEMENTS / VITAMINS are very much necessary in day-to-day life.

Adaptive has sub classifications such as

  • Natural -Passive such as antibodies received thru mother’s milk.
  • Artificial-active such as vaccination
  • Artificial passive: injecting antibodies (developed from others)
