This ensures that the total mortality for any geographic area and gender is the same as Morris et al. , while maintaining an estimated distribution across wealth quintiles based on individual risk factors and quantitative relative risk estimates from the literature. Rotavirus mortality burden is estimated as deaths per 1000 live births. equation(2) RVBurdenr,q,s=RVMortr,s⋅RVRiskIndexr,q,sRVRiskIndexr,s All subpopulation means were calculated using appropriate sample weights
CH5424802 solubility dmso based on the design of each survey. Mortality risk was converted into Disability Adjusted Life Years (DALYs) based on standard methods using age weighting and discounting  and . Previous studies have shown that over 98% of DALYs associated with rotavirus diarrhea in low income settings are associated with mortality  and , as a result we have not estimated DALYs associated with morbidity from acute cases. We estimated SCH727965 timing of projected deaths by combining overall rotavirus mortality estimates for each subpopulation and the estimated age distribution of events from Morris
et al. , combined with additional data from Clark and Sanderson  and . Monthly rates were estimated for the first year of life, and annually for the subsequent 4 years of life. For any subpopulation and period t, mortality burden is estimated in Equation (3), as: equation(3) RVBurdenr,q,s,t=RVTimet⋅RVBurdenr,q,sRVBurdenr,q,s,t=RVTimet⋅RVBurdenr,q,swhere RVTimet is the fraction of deaths occurring in time period t. We estimated the coverage of a ‘generalized’ 3-dose rotavirus vaccine that would be delivered alongside DPT1–3 through a routine immunization program. Vaccine effectiveness was estimated for each subpopulation based on estimated coverage of each of three doses, the expected timing of receiving each dose, and expected efficacy of each dose over time. Vaccination coverage was estimated by geographic area, gender and wealth quintile. Dipeptidyl peptidase Due to concerted national and state efforts, coverage of routine vaccinations in India is
rapidly improving. We used three alternative sources to estimate coverage: 2005–2006 NFHS-3 , 2007–2008 District Level Health Survey (DLHS-3) , and the 2009 Coverage Evaluation Survey (CES) . A fourth survey, the Annual Health Survey ,  and , was also consulted but it does not provide national estimates and was used descriptively. For the NFHS and the DLHS3, we estimate coverage of DPT1, DPT2 and DPT3 for each geographic area r, sex s and wealth quintile q sub-population. Vaccination timing was estimated for all three doses using vaccination data for 1-year-olds from DLHS-3. Specifically, for each subpopulation we estimated the proportion of children receiving each dose by the end of each time period t.
