Simple tricks may soothe baby vaccine pain
NCT ID NCT07185152
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested two simple methods—mechanical vibration and flick tapping—to reduce pain in 80 infants receiving their second hepatitis B vaccine. Babies were randomly assigned to one of the two techniques, and researchers measured pain scores, crying time, and vital signs. The goal was to find a safe, non-drug way to make shots less stressful for babies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mechanical vibration and flick tapping
- What this could lead to
- If effective, these simple techniques could offer drug-free ways to reduce pain and crying in babies during routine vaccinations.
- What could go wrong
- This is a small, completed study with only 80 infants, so results may not apply to all babies or other vaccines. The methods may not significantly reduce pain in real-world settings.
