Fig 1. Measles IgG seroprevalence measured by ELISA in different age groups from representative populations of Lao PDR, 2014.

*An ELISA value of 120 mIU/mL was considered positive. †Individuals 5–14 years old and 15–21 years old were among the targeted age groups of supplementary immunization activities conducted in 2011 using the MR combination vaccine with coverage of 97%. Their IgG prevalence was estimated to be 86.8% (95% CI: 83.0–90.6).
