Understanding Flu Vaccine Response in Pediatric Cancer Patients

This study looks at how well the seasonal flu vaccine works in children (up to 18 years old) who have a blood cancer (hematologic malignancy) and are receiving care at St. Jude Children's Research Hospital. Researchers want to see if these children develop a good immune response to the vaccine. This is important because flu can be very serious for children undergoing cancer treatment. You would be eligible if you have a blood cancer and are able to receive the current seasonal flu vaccine. The study aims to understand how many participants develop an immune response 3 to 5 weeks after vaccination, with results measured over 3 years. The current status of this study is unclear.

Study design
This is an observational study, meaning researchers will watch and collect information without providing any specific treatments. It plans to enroll 150 participants.
What's involved
You would have about one teaspoon of blood collected up to 6 times over a year. Researchers will also review your medical records for information on your condition, flu tests, and overall health.
Compensation
Not stated in the trial record.
Follow-up
The study will measure outcomes up to 3 years after vaccination.

Eligibility criteria

Inclusion

Patient ≤ 18 years old at the time of consent receiving care at St. Jude Children's Research Hospital
Diagnosed with a hematological malignancy
Eligible to receive the current seasonal influenza vaccine
  • Proportion of evaluable participants.3 years

    Feasibility is estimated as the proportion of evaluable patients who provide a baseline and Day +35 sample. A 95% confidence interval will be provided.

  • Proportion of participants with immunogenicity 3 to 5 weeks following vaccination.3 years

    Immunogenecity will be measured by the development of cell- and antibody-mediated influenza specific responses 3 to 5 weeks following vaccination. Immunogenicity is estimated as the proportion of evaluable patients whose cell- (as measured by development of any detectable specific T cell responses) and antibody-mediated influenza specific responses (as measured by detectable post vaccination antibody titers) 3 to 5 weeks following vaccination. 95% confidence intervals will be provided.
