Herd Immunity Formula: Critical threshold \( H_c = 1 - 1/R_0 \). When uptake \( V < H_c \), the effective reproduction number \( R_e > 1 \), allowing sustained epidemic chains.

Non-Linear Outbreak Dynamics: A 7% drop in coverage (95% → 88%) doesn't cause a 7% increase in cases—it triggers a 25x–50x surge in outbreak size due to contact percolation.
