Mathematical modelling has been a key component of both real-time decision-making and longer-term planning for COVID-19 and has been widely used to inform decisions on vaccine strategies. I will discuss our work on developing mathematical models for SARS-CoV-2 transmission, incorporating complexities such as age-based vaccine distribution, and the immunological mechanisms underpinning COVID-19 vaccine protection. I will further describe how we used these models to simulate future vaccine booster dose strategies for COVID-19 in representative country settings, considering the potential future emergence of new variants with modified transmission, immune escape, and severity properties. I will present broad findings and discuss the extent to which future regular vaccine boosting in high-risk populations has the potential to mitigate the global impact of COVID-19.

Alexandra Hogan is a mathematical infectious disease modeller, focussed on using modelling to quantify the public health impact of new vaccines. The focus of her current research is to dynamic models to help inform longer term planning of ongoing COVID-19 vaccination programs in Australia and the broader region. She is funded by an NHMRC Investigator Grant (Emerging Leader 1) and is a Scientia Lecturer within the School of Population Health, UNSW.
