One month described recruitment
The one-month milestone was randomization. Study participation and follow-up lasted approximately a year, so recruitment speed and completion describe different parts of the study.
Phase 1/2 · Influenza immunization
47 randomized in one month. All 47 completed.
Early private-practice engagement and community outreach supported recruitment. Continued communication then carried those relationships through approximately a year of participation and follow-up.

The work behind the result
Recruit quickly. Stay connected for the long term.
The initial recruitment window and the full participation period called for different kinds of support.
Recruiting a substantial group quickly
The team needed to introduce the study to a sizeable group of potential participants.
How WCR responded
WCR informed private-practice patients about the upcoming opportunity early. Community outreach also supported recruitment around the site.
A much longer participation commitment
A short recruitment period was followed by approximately a year of study participation.
How WCR responded
Many participants already knew the investigator’s practice. The research team strengthened those relationships through continued communication.
Connection through follow-up
Recruitment was only the beginning of the participant relationship.
How WCR responded
The team maintained contact through the study and follow-up, giving participants an ongoing connection with familiar staff.
Outcomes in context
Everyone in the randomized group completed
All 47 completed the entire study and follow-up. The reported record also included zero screen failures, zero early withdrawals, and zero losses to follow-up.
