Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Within the e-mail message, participants will indicate whether or not they intend to get vaccinated. Intention serves as an indirect dependent outcome. Upon clicking to indicate their intention, participants are redirected to a page which gives further instructions on how to proceed.
Participants who vaccinate will be asked to complete a brief follow-up questionnaire to evaluate their experience with vaccination and (for those offered and incentive) to provide contact information to receive their payment.
