Case Study: Immunointercetption And Vaccine

Immunointerception and Vaccine
Introduction :
Hello students, in this episode we are going learn about Immunointercetption and vaccine. The field of immunology has great promises with regard to the prevention and treatment of a wide range of infectious disease, inflammation, autoimmune diseases, and allergies. The immune system is one of the most complex biological systems in the body. Basic role of immune system involves distinguish self from non – self. This non – self can be an infectious agent, a transplanted organ or an endogenous cell that can be mistaken as a foreign. Immunointerception includes use of substance that are capable of interacting with immune system to modulate specific aspect of the hos response. Immunointerception involves immunomodulators and immunization by vaccines. Immunomodulators can be some bacterial product, lymphokines and plant derived substances. They can either stimulate or suppress the

M. bovis is grown on a medium containing high bile concentration for 13 years. It is suitable to use as a vaccine for tuberculosis.
OPV vaccine – Sabin Oral Polio vaccine
OPV vaccine is prepared with attenuated polio virus strain. Attenuation is achieved by growing polio virus in monkey kidney epithelial cells. OPV vaccine consists of 3 attenuated strains of polio viruses. It is administered orally to children on a sugar cube or in sugar liquid. The viral strains colonize in gut and induces protective immunity. It mainly induces production of IgA, IgM and IgG.
Advantages :
 Infectious microbes can stimulate generation of memory cells for cellular as well as humoral immune responses.
 It requires only a single immunization and no need of repeated booster doses since it multiply in host.
 Whole microbes stimulate response to antigens in their natural conformation. They raise immune response to all protective
