  1. Mean age of children in each study and expected duration of DCC attendance (see S2.2 for details) are given in months. Vaccination proportions per year were extracted from the children that that received at least one dose of PCV7 across the studies. When information on vaccination coverage for intermediate years was missing, the same value as in the preceding year was assumed.
