Figure 2.

Estimated impact of pneumococcal conjugate vaccine among children aged 2–59 months in 10 Latin American and Caribbean countries. Rate ratios were calculated by dividing the cumulative number of observed pneumonia deaths by the cumulative number of predicted pneumonia deaths during the evaluation period. Black squares represent the point estimates of rate ratio and bars represent their 95% credible intervals. The size of squares is proportional to the average number of pneumonia deaths per year, which is a proxy of sample size. Abbreviation: CrI, credible interval.
