Evaluation of the measles antibody titer in military recruits

Measles is a highly infectious virus and human is the only natural host of this virus. This study was carried out to examine the insolubility of vaccine-induced antibodies. This cross-sectional study carried out in Tehran، Iran. Obtaining consent، the blood was collected from 810 male at the age of 19 years old. Then we used ELISA to assess the measles antibody titer. Then، the executor completed the form which included demographic information، vaccination، past medical history and laboratory data for each participant. Our results show that out of 810 cases 67. 7% were still seropositive for measles. 50% of all participants had received measles vaccination. There was a significant relationship between measles antibody titer and all variables. The vaccination-induced measles virus antibodies decline in duration of time. Declining titers suggest the need for vigilance in ensuring disease protection for the vaccinated population. According to measles incidence rate and its bioterrorism danger for military the present study suggests that new military students should be revaccinated for measles disease.
