Immunization coverage of the world’s children
Immunization is a proven tool for combating diseases of infectious etiology, which pose a threat to human life, as well as their elimination.
For the first time to practice the use of vaccines began during the epidemic of smallpox, a disease that took many lives. At the end of XVIII English doctor E. Jenner noticed that a person infected with cowpox became resistant to infection with natural smallpox. The English doctor introduced a boy of eight years of contents from the vials to a milkmaid hand, infected with cowpox, and the child developed immunity to a smallpox. This discovery was a turning point in the history of vaccine prevention.
The success of immunoprophylaxis made it possible to achieve a significant reduction, and in some cases, elimination of dangerous infections. At present, a vaccination calendar has been introduced into pediatric medical practice, immunization against such infections as tetanus, whooping cough, poliomyelitis, measles, infectious parotitis, rubella and a number of other infectious diseases.
The following facts are indicative of the need for timely immunization of the population:
- Vaccination makes it possible to prevent the development of the disease, and hence suffering, disability or death from diseases against which immunoprophylactic drugs are developed.
- The global level of immunization coverage of the population demonstrates stable indicators.
- Currently, between two and three million deaths per year does not occur as a result of vaccination of the population.
- But according to WHO estimates, more than 22.5 million children of the first year of life in the world still do not receive basic vaccines.
