Individual factors influencing public's perceptions about the importance of COVID-19 immunity certificates: a cross-sectional online questionnaire survey in the UK

BACKGROUND

Understanding how perceptions around immunity certificates are influenced by individual characteristics is important to inform evidence-based policy making and implementation strategies for services around immunity and vaccine certification.

OBJECTIVE

To assess what were the main individual factors (including health beliefs about COVID-19, vaccination views, socio-demographic and lifestyle factors) influencing people's perception of the importance of using COVID-19 immunity certificates.

METHODS

Cross-sectional online survey with a nationally representative sample in the UK, conducted on the 3rd of August 2021. Responses were collected and analysed from 534 participants, aged 18 and older, residents of the UK. The primary outcome measure (dependent variable) was the participants' perceived importance of using immunity certificates, computed as an index of six items. The following individual drivers were used as the independent variables: a) personal beliefs about COVID-19 (using constructs adapted from the Health Belief Model), b) personal views on vaccination, c) willingness to share immunity status with service providers, and d) variables related to respondents' lifestyle and socio-demographic characteristics.

RESULTS

Perceived importance of immunity certificates was higher among respondents who felt that contracting COVID-19 would have a severe negative impact on their health (β=0.2564, P<.001=0.0000) and felt safer if vaccinated (β =0.1552, P<.001=0.0000). The prospect of future economic recovery positively influenced perceived importance of immunity certificates. Respondents who were employed or self-employed (β=-0.2412, P=.0010), or experienced an increase in income after the COVID-19 pandemic (β=-0.1287, P=.0020) perceived less important the use of immunity certificates compared to those who were unemployed or had retired or those who had experienced reduction in their income during the pandemic.

CONCLUSIONS

The findings of our survey suggest that more vulnerable members in our society (unemployed or retired and those believing that COVID-19 would have a severe impact on their health) and people who experienced a reduction in income during the pandemic perceived the severity of not using immunity certificates in their daily life as higher.

CLINICALTRIAL

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.

Big data analytics and COVID-19 vaccine

COVID-19 has severely affected almost every aspect of society worldwide. During the uncertainties of this pandemic, COVID-19 vaccines were a new hope. In particular, Covid's monitoring of the information, big data analysis played a major role. What started as the basic use of big data analysis is the core component of worldly initiatives Therefore, based on enlightening experiences of big data application for fighting the pandemic, this research focuses on the ethical objectives to be promoted in vaccine delivery, assessing the potential effect of big data analytics on reaching these goals by enabling people to receive a digital passport or certificate.

Why 'one size fits all' is not enough when designing COVID-19 immunity certificates for domestic use: a UK-wide cross-sectional online survey

OBJECTIVES

The present study explored public's willingness to use COVID-19 immunity certificates across six different domestic scenarios.

DESIGN

Cross-sectional online survey.

SETTING

UK representative survey conducted on 3 August 2021.

PARTICIPANTS

534 UK residents over 18 years old.

INTERVENTIONS

Participants replied to the same set of questions.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome measure was willingness to use immunity certificates across three different domestic settings: (1) visiting the general practitioner (GP) for a non-urgent health issue; (2) dining in a restaurant and (3) attending a performance in a theatre. For each setting two options, one prioritising convenience (option A) and the other privacy (option B), were offered. Our secondary outcome measures were computed indices from items adapted from the Health Belief Model; attitudes towards sharing immunity status with service providers; prior to COVID-19 lifestyle. In addition, we recorded data about respondents' sociodemographic characteristics.

RESULTS

Respondents were more willing to use immunity certificates that prioritised convenience (92%), rather than privacy (76%), when visiting their GP . However, privacy was more favourable in the other two settings (dining in a restaurant (84%) and going to a theatre (83%)) compared with convenience (38% and 39% respectively). Personal beliefs about COVID-19 and immunity certificates were associated with variations in willingness to use these across all scenarios. No variations were observed across sociodemographics and lifestyle.

CONCLUSIONS

The findings of this survey suggest that there is not one-size-fits-all solution for designing immunity certificates. Immunity certificates are complex sociotechnical systems, any attempt to implement these for domestic use should be tailored to different settings and user needs. The design of certification services requires a more evidence-based approach and further research is needed to understand how different settings, design elements (like convenience or privacy) and personal beliefs about the pandemic should inform their design.
