First seen Jun 27, 2026 · Last updated Jul 24, 2026 · Updated 2 times
Summary
This study looks at how well the immune system works in children who have finished cancer treatment. It aims to see if restarting vaccinations just 3 months after therapy is safe and effective. Researchers will compare giving a single booster shot versus a full series of vaccines to find the best way to protect these children from serious infections.
