The paper “When to boost: How dose timing determines the epidemic threshold” has been published in Physical Review Research.
In this work, we study how vaccination scheduling affects epidemic spreading. We show that at low vaccination rates the optimal strategy is to prioritize first doses, while at high vaccination rates alternative dose scheduling strategies outperform first-come first-served approaches.
We identify the threshold separating these two regimes and analytically derive the optimal prioritization scheme and interdose interval.
