Study Summary

The goal of this study is to develop evidence-based messages that effectively mitigate concerns of people at risk for not being vaccinated against COVID-19, with the ultimate goal of maximizing vaccine uptake in vulnerable populations. The investigators will collect data on COVID-19 disease and vaccine knowledge, beliefs, and intent to be vaccinated from an existing online panel. Results from this data collection will be used to develop effective messages and communication strategies. The investigators will test alternate versions of messages intended to reduce vaccine hesitancy and promote vaccine uptake among vaccine-hesitant individuals. This project will ultimately result in a set of tested, evidence-derived messages about vaccination for COVID-19.

Primary Outcome

Response options included yes, no, not sure. For participants whose initial vaccination intent was "not sure", a response
