What is the time commitment for participating in a vaccine trial?
The time commitment varies from study to study. In general, the first few visits are the longest because you are learning about the study, reviewing and completing the informed consent form, and undergoing the screening physical and tests. Each study is different, but visits will require anywhere from 30 minutes to 3 hours. A typical trial lasts between 12 and 24 months and requires between 6 and 20 visits.
