Epidemiology Engine

Disease spread modeling meets economic reality.

VacStak's epidemiology layer goes beyond ROI calculators — it models disease dynamics, predicts outbreak scenarios, and quantifies the economic value of vaccination coverage thresholds before outbreaks occur.

VS5·01
SIR / SEIR Disease Spread Model
Susceptible-Infected-Recovered dynamics with vaccination coverage overlay. Models R₀, herd immunity threshold, and peak infection burden across herd sizes.
VS5·02
Herd Immunity Threshold Calculator
Calculate the minimum vaccination coverage required to prevent outbreak propagation for any disease with known R₀ value. Species-specific contact rate adjustment.
VS5·03
Outbreak Probability & Cost Model
Monte Carlo simulation of outbreak probability given current coverage, herd density, and biosecurity practices. Outputs expected annual disease cost vs vaccination program cost.
VS5·04
Spatial Risk & Regional Pressure Score
USDA APHIS surveillance data integration — regional disease pressure scoring, proximity risk modeling, and seasonal transmission adjustment for location-specific vaccine decisions.
VS5·05
Vaccination Coverage Gap Economics
Economic value of closing vaccination coverage gaps — from current coverage to herd immunity threshold. Translates immunological targets into dollar-per-head financial decisions.
