  1. The movement of the vaccinated population aged 10 – 19 years of age is tracked through the life table. Columns Ix describes the impact of the intervention in terms of mortality reduction, columns Tx reflects the combined years lived with and without the intervention and columns ex reflect the increase in life expectancy attributable to the intervention
  2. Ix – individuals surviving, Tx – cumulative years lived, ex – remaining life expectancy at age x
