What is the Immune System

Immunization Program

Immunization, infectious diseases due to have the same mechanisms, one of the development, reflected in another. Thus, advancing vaccine technology has played a big role in our understanding of infectious diseases.

Before 1955, there were few widely used vaccines. These are more of diphtheria, tetanus, flowers, TAB, and BCG vaccines, respectively.

Virus cultures can be made, by opening up new horizons in immunity has enabled the development of virus vaccines. Today, A, C, Y and W-135 type of meningitis, typhoid polysaccharide vaccines against pneumococcus and VI are no longer available.

Other bacterial and viral vaccines and genetic engineering as a product of those of synthetic ones, will be available in the coming years. Parasitic diseases and also the possibility of immunization against dental caries, is increasing day by day.

No longer the slightest doubt about the beneficial effects of immunization do not even have one. The latest declaration of the DSO; smallpox immunization is widely applied in countries of the earth has been deleted and whooping cough, diphtheria, diseases such as highlights disappeared.

Immunity Booster

A high number of vaccines we have this quality of immunity from vaccines, injections, with the timing of the vaccines and immunity as a whole will be provided one by one, and detection of diseases and new vaccines, including the determination of a new immunization program in the form of what should be the problem, summarize the global immunization strategy related, leads to the emergence of specific questions. In addition, a disease that is completely destroyed from the earth, mass vaccination and immunization issues must respond to the question of what should be done.

Immune programs and information on the epidemiology of the disease, as well as vaccinated individuals are prepared according to the immune response. These factors are shaped by recent suggestions and previous immunization programs in applied data showing the degree of success or failure are considered.

A large section of the population vaccinated, for example contributing to the development of specific antibody and at least 95'% during an epidemic or disease in a significant percentage of people who are experiencing to obtain full protection, immunity applied to evidence that the program is considered effective.

All epidemiology of the disease, most children with this disease face period, infection, disease severity at different age levels and ability to respond to stimuli the child's vaccination / attachment factors such as variation, immunity should be considered before designating the program.

Real immunization programs should be developed in accordance with the rules determined by looking at specific diseases, epidemiological characteristics. 6 After months, a major threat to children. Measles is extremely dangerous to children in developing countries, and often result in death, but the industrialized countries are at an early age and usually larger than benign. Very severe course of whooping cough in the first months of life, of making the vaccine indicate that as early as possible. Tuberculosis vaccine requirement, the prevalence of the disease varies from country to country, depending.

In all this time, developed a specific, identified an "ideal" epidemiological model, a large change as a result of a vaccination campaign, or granting of new vaccines on the market. In other words, the immune programs fitting the new conditions, or in other words, the recorded changes in epidemiology of infectious diseases and must be customized according to experience in this field.
A reduction in the incidence of infectious disease or to be able to taking control of the following three conditions are required.

1. Must have obtained a sufficient amount of vaccine;
2. All activities during periods of storage and use of these vaccines should not lose anything.
3. Depending on the vaccine used, the individuals at risk for at least 80-to 95% enforced.

Expanded program of immunization (EPI), the results and experiences gained in industrialized countries, has proved to be contained in childhood infectious diseases.
An immunization program should be followed strictly the rules does not occur. This program is not only the child's ability to win immunity, epidemiology, and microbial or viral disease, live or killed, either alone or together with the quality of the vaccines, the antigenic considering a "priority program" is.
