These next questions are additional COVID-related questions that we ask everyone to try and reduce the likelihood of exposure to, and spread of, COVID-19 for participants and study staff. You must answer all of these questions to be considered for the research study. But, if you are not comfortable answering, you may withdraw from this screening process and we will consider you for future studies that might not include these same questions.
1. Have you been fully vaccinated against the COVID-19 virus? (“Fully vaccinated” is defined as two weeks having passed after receiving the second dose of the Pfizer, Moderna, or AstraZeneca vaccine, or two weeks having passed after receiving the single dose of the J&J Janssen vaccine.)
