Vaccine effectiveness of receiving at least two doses of the 10-valent pneumococcal conjugate vaccine (PCV10) vs. none against ultrasound-confirmed pneumonia when compared with clinic controls in 3 subdistricts in Sylhet, Bangladesh (July 2015–September 2017). A Displays a forest plot of unadjusted vaccine effectiveness of ≥ 2 doses of PCV10 vs. none stratified by consolidation size, laterality, and by age or sex. B Displays a forest plot of vaccine effectiveness adjusted for household characteristics, assets, maternal education, whether the father resides in the household, number of children aged under five years living in the household, whether the family owns the house, family owns a clean stove, whether the mother participates in decision making, and propensity to seek care for the child. We stratified cases by consolidation size and, evaluated for interactions between consolidation size (≥ 1.5 or 1–1.49 cm) and laterality. Vaccine effectiveness is represented with a diamond, and the horizontal line is the corresponding 95% confidence interval. The size of the diamond is proportional to the sample size used for each analysis
