  number_of_events,
  number_of_events_averted,
  population_size,
  vaccine_effectiveness
)

Value

Details

The number of individuals needed to vaccinate to prevent one event is calculated as described by Machado et al. (2019) doi:10.2807/1560-7917.ES.2019.24.45.1900268.

Examples

data(ve_mock_data)
coverage <- coverage_and_incidence_mock_data$coverage_data
incidence <- coverage_and_incidence_mock_data$incidence_data

nae <- compute_events_averted_by_vaccination(
  number_of_events = incidence$events,
  cumulative_coverage = coverage$cumulative_coverage,
  vaccine_effectiveness = vaccine_effectiveness
)
