Seroprevalence of IgG antibodies against measles and rubella viruses before and after the MR-SIA, by district

Bars represent the weighted seroprevalence estimates for the pre-MR-SIA serosurvey and the post-MR-SIA serosurvey. Lines at the top of each bar represent 95% CIs. Age-specific weighted seroprevalence of IgG antibodies against measles and rubella viruses were estimated with Wald 95% CIs (black bars) using a random-intercept logistic regression model that included sampling weights based on survey design. Equivocal results were classified as seropositive. SIA=supplementary immunisation activities.
