Can text messages and phone calls boost HPV shots in rural kids?
NCT ID NCT06738355
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tested different outreach methods—like automated calls, texts, and emails—to encourage parents in rural areas to get their children (ages 9-17) the HPV vaccine. The study involved 335 parents and caregivers at four community clinics in rural Washington. The main goal was to see if a larger, full-scale trial is possible, not yet to prove the outreach works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- behavioral intervention (automated calls, texts, emails, mailings, live calls)
- What this could lead to
- If successful, this approach could help more rural children get the HPV vaccine, reducing cancer risk in underserved communities.
- What could go wrong
- This is a small pilot trial focused on feasibility, not on proving the intervention works. Results may not apply to other settings or populations.
