Abstract
This is the MATLAB source code for the SATvac (Stochastic Agent-based T-cell Vaccination) model, a stochastic agent-based framework for simulating CD8+ T cell dynamics following vaccination. This model captures main immune response phases including activation, expansion, and contraction. It also tracks T cell differentiation into effector and memory cell types and explains the variability observed in immune responses by modeling stochasticity at the single cell level.
