Calculate impact by calendar year

Calculate impact accrued over all ages for a specific year. This calculates the difference in disease burden between baseline and focal scenarios for a given year. The baseline scenario can have no vaccination or different coverage to the focal scenario. This aggregates the impact over all ages modelled. This does not account for the future disease burden averted through current vaccine activities.

impact_by_calendar_year(baseline_burden, focal_burden)

Arguments

baseline_burden

Data frame of baseline burden data this needs to have columns country, burden_outcome, year, age, value

focal_burden

Data frame of focal burden data this needs to have columns country, burden_outcome, year, age, value

Value

Vaccine impact by country and year for burden outcomes as a data frame with columns country, year, burden_outcome and impact
