US Gov & Yale Hold Clinical Trials To Test “Persuasive Messages For COVID-19 Vaccine Uptake”
In Brief
- The Facts:The US government and Yale University collaborate in a clinical trial to determine the best messaging to persuade Americans to take the COVID-19 vaccine.
- Reflect On:Why do people need to be persuaded? Is it possible they have a lack of trust in public health recommendations for good reason?
This study tests different messages about vaccinating against COVID-19 once the vaccine becomes available. Participants are randomized to 1 of 12 arms, with one control arm and one baseline arm. We will compare the reported willingness to get a COVID-19 vaccine at 3 and 6 months of it becoming available between the 10 intervention arms to the 2 control arms.Study participants are recruited online by Lucid, which matches census based sampling in online recruitment.

Other: Personal freedom message

Other: Community interest message
Other: Economic benefit message
Other: Guilt message

Other: Trust in science message
Other: Not bravery message
Primary Outcome Measures :
- Intention to get COVID-19 vaccine [ Time Frame: Immediately after intervention, in the same survey in which the intervention message is provided ]
This is a self reported measure, immediately after the intervention message, of the likelihood of getting a COVID-19 vaccination within 3 months and then 6 months of it becoming available. During analysis, responses among those assigned to different intervention messages will be compared to those in the control group.
Secondary Outcome Measures :
- Vaccine confidence scale [ Time Frame: Immediately after intervention, in the same survey in which the intervention message is provided ]
This is a validated scale. This scale will be used to assess the impact of the messages on vaccine confidence. (Outcome assessed only for the half of the sample that answers these items post-treatment)- Persuade others item [ Time Frame: Immediately after intervention, in the same survey in which the intervention message is provided ]
This is a measure of a willingness to persuade others to take the COVID-19 vaccine.- Fear of those who have not been vaccinated [ Time Frame: Immediately after intervention, in the same survey in which the intervention message is provided ]
This is a measure of a comfort with an unvaccinated individual visiting an elderly friend after a vaccine becomes available- Social judgment of those who do not vaccinate [ Time Frame: Immediately after intervention, in the same survey in which the intervention message is provided ]
This is a scale composed of 4 items measuring the trustworthiness, selfishness, likeableness, and competence of those who choose not to get vaccinated after a vaccine becomes available.
