We conducted a methodological study of COVID-19 vaccine allocation modelling papers, specifically looking for publications that considered equity. We found that most models did not take equity into account, with the vast majority of publications presenting aggregated results and no results by any subgroup (e.g. age, race, geography, etc.). We then provide examples of how modelling can be useful to answer equity questions, and highlight some of the findings from the publications that did. Finally, we describe eight considerations that seem important to consider when including equity in future vaccine allocation models.
Keywords: COVID-19; demographics; equity; review; vaccine allocation; vaccine prioritization.
