- Brief Summary
With the constant threat of new epidemic waves and the emergence of variants, COVID-19 resilience can only be attained when a sufficient level of immunity is achieved. Yet, in the US and the UK, COVID-19 vaccination campaigns have failed to secure consistent vaccination acceptance in racial/ethnic minority communities. Despite racial/ethnic minorities being more at risk from COVID-19, they are less vaccinated than the White majority. The investigators propose that current vaccination invitation messages are deemed less trustworthy by racial/ethnic minorities than the White majority and that this might partly explain reduced vaccination acceptance. To provide causal evidence of the role of trust and actionable insights, the investigators will experimentally assess the benefits of new invitation messages to receive the COVID-19 booster dose in large, racially/ethnically diverse samples in the US and the UK. Results will evidence how to increase message and source trustworthiness to foster trust and vaccination acceptance across racial/ethnic groups.

Group Intervention Description Low trust boost sender + high trust boost content Trust boost Participants will read the following text in an online survey: As your local GP, I would like to invite you to book your COVID-19 booster vaccination. The vaccine reduces your chance of becoming infected and protects you against severe forms of the illness. It also protects your loved ones by reducing the risk that you infect others. COVID can be severe, don't risk it. This vaccination is especially important for people who are at higher risk from COVID such as older individuals or those from ethnic minorities. Vaccines may cause side effects, but the benefits outweigh the risks. The most common side effects are very mild (e.g., sore arm, a fever) and severe side effects are very rare (e.g., allergic reaction).
