Expert elicitation on the relative importance of possible SARS-CoV-2 transmission routes and the effectiveness of mitigations.

Objectives: To help people make decisions about the most effective mitigation measures against SARS-CoV-2 transmission in different scenarios, the likelihoods of transmission by different routes need to be quantified to some degree (however uncertain). These likelihoods need to be communicated in an appropriate way to illustrate the relative importance of different routes in different scenarios, the likely effectiveness of different mitigation measures along those routes, and the level of uncertainty in those estimates. In this study, a pragmatic expert elicitation was undertaken to supply the underlying quantitative values to produce such a communication tool.

Correlates of intended COVID-19 vaccine acceptance across time and countries: results from a series of cross-sectional surveys.

Objective: Describe demographical, social and psychological correlates of willingness to receive a COVID-19 vaccine.

Setting: Series of online surveys undertaken between March and October 2020.

Participants: A total of 25 separate national samples (matched to country population by age and sex) in 12 different countries were recruited through online panel providers (n=25 334).

How do the UK public interpret COVID-19 test results? Comparing the impact of official information about results and reliability used in the UK, USA and New Zealand: a randomised controlled trial.

Objectives: To assess the effects of different official information on public interpretation of a personal COVID-19 PCR test result.

Design: A 5×2 factorial, randomised, between-subjects experiment, comparing four wordings of information about the test result and a control arm of no additional information; for both positive and negative test results.

Setting: Online experiment using recruitment platform Respondi.
