Summary

This study looks at whether sleep habits of 11-12 year olds affect their immune response to the meningococcal vaccine (MCV4). About 66 healthy teens will wear a sleep tracker and keep their normal sleep schedule for 5 weeks. Researchers will measure antibody levels after vaccination to see if sleep quality matters.

What this could mean

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

Active substance
MCV4 meningococcal vaccine
What this could lead to
If it works, this could show that good sleep helps vaccines work better in teens, leading to stronger protection.
What could go wrong
This is a small pilot study, so results may not apply to all teens. It only looks at one vaccine and doesn't test a new treatment.
