NCT ID NCT07338851
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 600 Chinese children who received standard vaccines against polio, measles, mumps, rubella, and hepatitis A. Researchers will test their blood to see if protective antibodies remain 5 years after vaccination. The goal is to understand how long vaccine protection lasts in real-world conditions.
What this could mean

What this could lead to
If successful, this study could confirm that these vaccines provide long-lasting protection, supporting current vaccination schedules.
