Immunity against measles among vaccinated school going children in Zahedan, southeast of Iran.

Measles is an important childhood disease and an acute viral infection, which is very contagious and recovery from it is the rule. But serious complications of the respiratory and central nervous system may occur. Measles can be prevented with live, attenuated vaccine. In our country (Iran), despite the use of vaccine since 1976, we are still having local epidemics especially in the children aged 15-20 years. Therefore the present study was conducted to deteminate the level of immunity in this target population in Zahedan.
