Understandings and practices related to risk, immunity and vaccination during the Delta variant COVID-19 outbreak in Australia: An interview study

BACKGROUND: The aim of this study was to use indepth social research to better understand the relationships and intersections between understandings and practices of COVID-19 risk, immunity and vaccination in lay people’s accounts. METHODS: This article reports findings from a qualitative research project involving semi-structured telephone interviews with a diverse group of 40 adults from around Australia about their experiences of the COVID crisis, conducted in late 2021 during the Delta variant outbreak. The participants’ responses to questions about COVID risk, COVID vaccines and how they thought they could best protect their health were analysed using an inductive thematic approach. RESULTS: A notion of ‘communal risk’ was expressed together with ‘individual risk’. Relatedly, people’s understandings of what might be characterised as ‘communal immunity’ as well as individual immunity also dominated in their accounts. Both communal risk and communal immunity are influenced by a range of constantly changing and interrelated factors. Locale was a strong factor in shaping people’s experiences and stances related to COVID risk. The participants referred to aspects such as their community’s geographical location; the number of COVID cases and the level of COVID vaccination by others living in their state or territory; adoption of preventive measures; vaccine availability, scheduling and take-up; viral testing and tracing reporting; and the extent and timing of viral spread in the population. These factors were continually related back to highly specific conditions and practices in their community or state of residence. CONCLUSIONS: Understandings and practices related to COVID risk, immunity and vaccination were based both on individual experiences and broader ideas about the role of community. Spatial contexts are influential but there is also a strong temporality to these understandings and practices. There is a fine balance to be maintained between individual-level protection from COVID risk and community-level actions.
