Official title

A Prospective Cohort Study to Define Infectious Burden, the Seroprevalence of Vaccine Preventable Pathogens and Immune Recovery in the First Year Following Completion of Therapy in Patients With Acute Lymphoblastic Leukemia (ALL)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This observational study aims to assess recovery of the immune system and immunity to vaccine-preventable diseases in children, adolescents, and young adults who recently completed treatment for acute lymphoblastic leukemia (ALL). Several children's hospitals in the United States are participating in the study, which will enroll up to 100 pediatric participants. The study is intended to determine the rate of infection after leukemia treatment and to inform future studies and recommendations about whether children and adolescents who have leukemia should receive additional vaccine doses or boosters after treatment.
