We then obtained the 3–5-year incidence rate by applying to the 0–2 year incidence rate the relative proportion of cases that were 3–5 year old in the IRSSN study. Cumulating the incidence risk in the 4 months to 2 years with that in the 3–5 years provided the 4 months to 5 years risk of rotavirus related events. The number needed to vaccinate (NNV), DNA-PK inhibitor under assumptions of no indirect effect, is provided by the inverse of the product of vaccine efficacy and absolute risk in the unvaccinated. We assumed

national immunization coverage to be 74% and no herd protection while projecting the events averted. The data for estimation of healthcare costs of rotavirus disease was obtained from two published studies [21] and [22], conducted in 2006 and 2009 respectively, that used the WHO generic protocol [23] to estimate the economic burden of diarrhea including direct medical and selleck screening library non-medical (e.g., travel costs to and from the hospital) costs through review of patient

charts, healthcare facility records, pharmacy records, and patient family interviews. Healthcare costs, both hospitalizations and outpatient visits, were divided into three levels – primary, secondary, and tertiary. Secondary and tertiary level outpatient visits were further divided into two categories – those that occur in ambulatory clinics and those that occur in emergency rooms. It was assumed that 15% of all outpatient visits for secondary and tertiary level care occurred via emergency visits and 85% occurred via ambulatory clinics. Also, the proportion of rotavirus-related visits to primary, secondary and tertiary levels of care were considered to be 33%, 41% and 26% respectively, based on a multi-country estimate of healthcare utilization patterns [24]. The healthcare costs were calculated Thymidine kinase by using weights by the proportion of population that sought each level of care and then multiplied by the total number of events. The total cost of rotavirus-related hospitalizations and outpatient

visits in Indian children was calculated by multiplying the total number of yearly healthcare encounters attributable to rotavirus for children <5 years of age by the costs of each encounter, weighted for the proportion of population that sought each level of care. All costs are reported in 2013 Indian rupees, adjusted for inflation. The Consumer Price Index (CPI) for India published by the World Bank was used for inflation-adjustment [25]. Total costs are also reported in U.S. dollars (1 USD = 60 INR). Rotavac® was assumed to cost INR 50 per dose. It was also assumed that it would be administered within the current National Immunization Schedule and the incremental administrative cost per dose would not be more than INR 5 per dose. The total cost of vaccinating 1 child with 3 doses of Rotavac® is estimated at INR 165.
