Summary

This study tested whether sending text message reminders to parents could increase routine vaccination rates in children aged 0-2 years. Over 1,000 families in Brooklyn, New York, whose children were behind on vaccines received texts when shots were due or coming due. The goal was to help kids get back on schedule after COVID-19 lockdowns disrupted well-child visits.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: text messaging
What this could lead to: If successful, this simple texting approach could help more young children get their routine vaccines on time, reducing the risk of preventable diseases.
What could go wrong: This is a completed behavioral study, not a drug trial. The results may not apply to other communities or settings, and texting alone may not overcome all barriers to vaccination.
