Abstract
The goal of this study is to determine how information campaigns that explain different benefits of widespread vaccination against COVID-19 affect vaccine uptake. We will conduct a survey experiment where participants will be exposed to 1 of 9 different information treatments including: a no information, control treatment, information explaining the economic benefits of taking the COVID-19 vaccine, the public health benefits of widespread vaccination against COVID-19, the private health benefits of vaccinating against COVID-19, and combinations of private health benefit, public health benefit, and economic benefit messages, and the vaccine trial process.

Experimental Design

Experimental Design
Participants will be randomized into 1 of 9 different information treatments where they will be informed of the private health benefits of vaccination, the public health benefits of vaccination, the economic benefits of vaccination, a combination of private, public and economic benefits, or the vaccine trial process. Participants will then be asked about their willingness to take a COVID-19 vaccine. In the second part of the survey, participants will be asked about how they have been affected most by the pandemic, what they worry about most, the extent they are complying with social distancing and mask wearing, and how disruptive the pandemic has been in terms of health and employment.
