Immunoprophylaxis of Measles in Organized Collectives at the Stage of Measles Virus Infection Elimination
Military elements, which belong to organized collectives, are contingent of high-risk of measles infection spread. In this regaraone of the most effective preventive measures is immunization of military against measles infection. For the purpose of evaluating the efficacy of vaccine prophylaxis serologic testings to determinate measles antibodies of the military, depending on their age and duty station have been held in military collectives. The results of serologic screening showed that measles protection rate among the military averaged 74,8±0,9% with variations from 63,5±2,0% for contract military up to 78,7±1,2% for the students of Samara Military-Medical Institute. For compulsory military the rate of immune interlayer averaged out at 77,5±1,5%. Herewith significant difference depending on the duty station has been revealed: the lowest rate was detected in Samara military reservation (70,4±3,2%), the highest - in Chelyabinsk military reservation (84,0±2,7%). High percentage of the military, susceptible to measles infection (25,2±1,2%), under the condition of permanent «intermixture» allows to classify military elements as a group of high-risk measles infection. Therefore measles immunization tactics for the military should be based on differentiated approach, depending on the age, immunization history and military contingent. When formatting military collectives it is necessary to perform selective serologic control of measles immunity in order to decide the issue of the military further immunization.
