 _{{ packagename }}_ provides estimates for the total proportion of a population infected over the course of an epidemic, and can account for a demographic distribution (such as age groups) and demography-specific contact patterns, as well as for heterogeneous susceptibility to infection between groups (such as due to age-group specific immune responses) and within groups (such as due to immunisation programs). An advantage of this approach is that it requires fewer parameters to be defined compared to a model that simulates the full transmission dynamics over time, such as models in the [_epidemics_ package](https://epiverse-trace.github.io/epidemics/articles/epidemics.html).

 _{{ packagename }}_ can help provide rough estimates of the effectiveness of pharmaceutical interventions in the form of immunisation programmes, or the effect of naturally acquired immunity through previous infection (see the vignette).
