Figure 1. Seropositivity (%) of anti-measles, rubella, mumps IgG antibodies of different age groups.

Panel A for anti-measles, Panel B for anti-rubella, Panel C for anti-mumps. Solid lines represents prevalence of seropositivity for measles antibodies (>200 mIU/mL), rubella antibodies (>20 IU/mL), mumps antibodies (>100 U/mL). Dashed lines respresent upper and lower limits of the exact binomial 95% confidence interval.
