Trial Summary

What is the purpose of this trial?

This trial tests if vitamin D3 can lower lung issues in kids with sickle cell disease. It compares different dosing schedules to see which works better. The goal is to find a simple, low-cost way to help these children stay healthier. Vitamin D has been studied for its potential to reduce respiratory complications in children with sickle cell disease due to its ability to fight infections and support the immune system.
