РАЗВИТИЕ НА ИМУНИЗАЦИОННОТО ДЕЛО В БЪЛГАРИЯ ПРЕЗ ВТОРАТА ПОЛОВИНА НА ХХ ВЕК
DEVELOPMENT OF IMMUNIZATION IN BULGARIA IN THE SECOND HALF OF THE 20TH CENTURY

Summary/Abstract: Tracing the history of infectious diseases, the control and success in combating them is, to a great extent, due to the widespread implementation of immunoprophylaxis. The aim of this study is to trace the historical development of immunization in Bulgaria in the second half of the twentieth century. Scientific literature, ordinances and documents regulating the organization for introduction of new vaccines into the country’s immunization calendar during the period under investigation have been studied using a documentary method. A historical analysis of the impact of vaccines on the spread of socially significant infectious diseases has been performed. The study demonstrates that a targeted immunization policy leads to a significant decline in the incidence of vaccine-avoidable infections, some of which reach the point of complete eradication (variola) and elimination (diphtheria and polio).
