what is a vaccine and how does it work

Vaccine is a biological medicinal substance made using the body of organisms, using which increases the body's ability to fight a particular disease.

By penetrating the various defense elements of the reer, the parasitic pathogenic bacteria or viruses enter the body and are able to produce diseases in their host's body by producing toxins. As a result, the cells of the body also produce antitoxin, antibody, or immune tody by the natural reaction against the aggressive growth of the organism and its producing microbes.

It takes several days for the germicide antibodies to develop. If the disease does not cause immediate death and sufficient opportunity is created for the formation of immunity, the invasive power of the pathogenic bacteria begins to decline and the chances of disease suppression are greatly increased. The bacteria for which antibodies are produced have a fatal effect on the same bacteria.

 Resistant to the bacterium of typhoid fever, they are capable of destroying the bacteria of intestinal fever, which are not fatal to the bacteria of dysentery or cholera. Antibodies are known to be caste-specific only because they are fatal to their producing antigen.

If the antibacterial antibodies of a particular disease in one's body are abundant before the infection of that disease is caused by the bacteria, then that bacteria is unable to produce the disease. If the amount of immunity is insufficient, there is a possibility of mild disease.

Due to the origin of immunological antibodies on infection, it has been observed that once a disease occurs, the same disease does not occur for some time (second). Once smallpox is present, there is often no possibility of getting this disease the second time. Some pediatric patients do not recur in their youth or old age when they are in infancy. On the basis of this principle, the prevention of the disease is done successfully by entering the immune body by vaccination or inoculation.

The main purpose of the vaccine is to produce immunity in the body without causing disease. Naturally, antibodies are formed due to the response to the disease, but vaccines are made to form antibodies in the body by waging a type of cold war. Immunities start to produce as soon as dead bacteria unable to produce disease enter the body.

Use of dead bacteria is necessary. It is necessary to use living bacteria in such a condition.
In such a state, the invasive power of living bacteria is first weakened and disposed of, so that they do not have the pathogenic potential, but the power to make immunity remains. This biology of bacteria that can produce organisms can be used in vaccines by relaxing with the combination of Pharmelin. This type of formalin affected organism is called Toxoid.

Thus, the vaccine is used to kill deadly bacteria, disinfected bacteria or biofilms to produce prophylactic antibodies. For prophylactic vaccines that are used in fluids. It is called a vaccine. It is actually a suspension of dead or defunct bacteria. Phenol or some other bactericidal substance is added to it to maintain the purity of the vaccine.
