Research-grade vaccine economics and epidemiology calculators for any species, any disease. Free and open access — the entry point to VacStak's decision intelligence platform.
Calculate the return on investment of any vaccine program. Compares vaccine cost against disease loss prevention value to determine net benefit and ROI ratio.
Calculate the minimum vaccination coverage required to prevent disease outbreak propagation. Based on the basic reproduction number (R₀) for the target disease.
Estimate the total economic cost of a disease outbreak before it happens. Models mortality loss, treatment costs, production losses, and biosecurity response costs.
Calculate the economic value of closing the gap between your current vaccination coverage and the herd immunity threshold. Translates immunological targets into per-head financial decisions.
VS0 is VacStak's free open-access storefront — the foundation of the world's first vaccine economics and epidemiology platform. These 4 calculators provide universal vaccine decision support applicable to any species and any disease, grounded in peer-reviewed immunology and agricultural economics research.
VS0 pairs Science (VS0-S.6001–6004) with Economics (VS0-E.6001–6004) — use the Science tab to model disease dynamics, then switch to Economics to translate those results into ROI decisions. For species-specific storefronts (VS1 Cattle, VS2 Swine, VS4 Poultry and more), upgrade to VacStak Pro →
