Discounted Dependency-free years gained until 65 years of age†		9.6 years	11.2 years	14.0 years

^*Weighted average based on 485 children receiving IBI (efficacy: 30% normal, 50% semi-dependent, 20% very dependent) and 824 children receiving no IBI (efficacy: 25% normal, 25% semi-dependent, 50% very dependent)

^†Calculated as a weighted average based on efficacy rates for each scenario, discounted at 3% per annum
