What is artificial immunity?
Artificial immunity is the means by which the body is given immunity to the disease with intentional exposure to a small amount. The most common form of artificial immunity is classified as active and comes in the form of vaccination, usually gives children and young adults. The passive form of artificial immunity involves the introduction of an antibody into the system as soon as the person has already been infected with the disease, which eventually alleviated the current symptoms of the disease and prevented again. Individuals were exposed to smaller smallpox tribes in a controlled environment. Once their bodies have formed natural immunity or resistance to weakened smallpox trunk, it was much less likely to be infected with fatal smallpox tribes. Basically, patients were given disease to help fight him later in life. Although this method was effective, scientists of time did not have real scientific knowledge of why it worked.
Louis Pasteur was famous inventingEzce, who created the theory of germ diseases. His work showed that the disease is often carried by bacteria and that once bacteria enter the body, there were several natural reactions that would start to fight them. Once the body has successfully got rid of the disease, the second infection with the same bacteria would prove harmless. Pasteur's theories have shown that once the body learns to fight specific diseases, it is then able to prevent reinfection independently.
One of the greatest complications with the pasteur's theory of creating artificial immunity was that certain diseases such as smallpox were caused by tribes of bacteria that have been slowly mutating over time. The mutability of these bacteria has often led to more vaccination. Because the bacteria have undergone significant changes, a new vaccine would have to be developed to provide people with the opportunity to fight new tribes. This is the primary reason why common diseases such as influenza often require new vaccination every year.
As far as passiveArtificial immunity, there are some diseases such as tetanus, which can only be vaccinated in the short term. Unlike smallpox vaccination, which can potentially protect the body from undefinously unhappy, it provides only artificial immunity for about seven years. Bacteria causing the disease itself does not necessarily mutate, as is the case with the flu; The immunity it creates has a rather limited period of efficacy.
