Figure 2
Impact of rotavirus vaccination on monthly events of childhood diarrhea deaths in Brazil by region.
Each analysis compares the monthly observed events among children under 5 y after rotavirus vaccination (2007 to 2009) with expected events in the absence of vaccination, by region. Expected number of events and 95% CIs are based on predictions from regression models fitted to historic data from each region (2002 to 2005).
