Immune Function and Vaccination After Pediatric Cancer Therapy

This study is for children and young adults aged 2 to 21 who have completed cancer treatment. It aims to understand how cancer therapy affects their immune system and their ability to fight infections. Researchers will evaluate immune function and vaccine protection over 2 years. If your child's vaccine protection is low, they will either receive booster vaccines or a full series of revaccinations (like those given after a stem cell transplant) using vaccines for diseases like Haemophilus influenza type B, tetanus, polio, and measles. The study will compare these two approaches to see which is better at restoring immunity. The goal is to improve protection against serious infections in pediatric cancer survivors.

Study design
This is a randomized study planning to enroll 64 participants. It will compare two different vaccination strategies.
What's involved
Participants will have lab evaluations for immune function at baseline, 3, 6, 9, and 24 months after finishing cancer treatment. Some participants will receive booster vaccines or a full revaccination series.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 2 years to assess vaccine protection.
