Abstract
Objectives: to evaluate the prevalence of mumps specific IgG antibodies in sera of different age groups and sexes of Mosul population.
Methods: 440 sera of different age groups and sexes were collected and tested by ELISA test.
Results: Seropositivity against mumps virus among different age groups was 68% (males 36% and females 32%, the difference was not significant). However, significant differences (p< 0.05) were seen among males and females at different age groups.
Conclusion: Seropositivity in age group 0-9 years which was within the introduction of MMR was the lowest. indicating that the level of immunity developed by MMR vaccine was below the herd immunity threshold.
