Changelog

multigroup.vaccine (development version)

multigroup.vaccine 0.1.1

  • Fixed bug in contactMatrixPolymod() where age limits exceeding 90 caused dimension mismatch errors. The function now warns and automatically adjusts age limits to 90, aggregating corresponding populations into the 90+ group. (#39)

multigroup.vaccine 0.1.0

Initial release of multigroup.vaccine, a package for examining the effects of differential vaccination rates in populations with different sizes, contact rates, and other epidemiological parameters.

New features

  • Multi-group vaccine modeling functions: getFinalSize(), transmissionRates(), getFinalSizeODE(), getFinalSizeDist(), and getSizeAtTime().

  • Interactive Shiny application via run_my_app() for exploring vaccine scenarios and visualizing effects of differential vaccination rates across population groups.

  • U.S. Census data integration: getCensusData() downloads and processes Census Bureau population estimates by age and county, with support for age-structured populations, sex disaggregation, and built-in caching. Helper functions include getCensusDataPath(), getStateFIPS(), and listCounties().

  • Contact matrix functionality using POLYMOD contact survey data via the socialmixr package for realistic age-structured epidemic modeling.

  • Example dataset UtahAgeCountyPop with 2024 population estimates by age group for all Utah counties.
