WCR-reported study results
Recruitment drew on practice and community access
WCR describes contacting practice patients and reaching into the surrounding community. The site randomized 47 participants during a one-month period. That concentrated enrollment period was followed by a substantially longer commitment to study participation and follow-up.
Completion is a separate achievement
The source reports that all 47 randomized participants completed the study and follow-up over approximately one year. It also reports no screen failures, early withdrawals, or loss to follow-up. The one-month period refers to randomization; it does not describe the length of participation.
Consider the whole communication plan
For a vaccine study, the site discussion should extend beyond how quickly candidates can be reached. It should also address reminders, symptom reporting, follow-up appointments, and staff continuity. WGR connects central recruitment with local study teams so the participant pathway remains visible after enrollment.
