NCT ID NCT07172074

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This completed study surveyed 1,786 US adults to understand which psychological traits—like needle fear, distrust, or open-mindedness—are most strongly linked to vaccine attitudes and history. Participants answered questions online about their feelings toward vaccines and which age-recommended vaccines they had received. The goal is to find new ways to encourage vaccination by targeting the right psychological motives.
