How best to prioritise COVID-19 vaccination within and between countries has been a public health and an ethical challenge for decision-makers globally, especially given the vaccine supply is limited in the short and medium term. Epidemiological and economic models can support this decision by providing an assessment of the potential health and broader societal impact of competing prioritisation strategies (e.g., age based strategies, strategies based on the occupation or social networks). This allows researchers to compare those strategies as identify the optimal groups to prioritise for vaccination, based on the main public health objectives and scenarios.
In this webinar, we will discuss the results from a systematic literature search and narrative review of mathematical modelling studies of the impact of prioritising COVID-19 vaccination to different target population groups. The search identified 36 studies in various settings (low, middle, high income settings), seeking to optimise different outcomes (deaths, cases, hospitalisation, economic outcomes), looking at various vaccine characteristics, and employing different modelling methods (although we only considered mathematical models of vaccination for the review). A link to the pre-print on Medrixv can be found here.
Those findings can be used to support the development of national prioritisation strategies, as well as international recommendations such as the WHO (through the SAGE working group on COVID-19 vaccines), which has developed a roadmap to prioritisation of groups for vaccination while supply is limited.
