Evaluation of Immunologic Response Following COVID-19 Vaccination in Children, Adolescents, and Young Adults With Cancer
An observational study of COVID-19 Infection and Hematopoietic and Lymphatic System Neoplasm, run by Children's Oncology Group at 72 sites in United States.
Trial summary
This study evaluates immunologic response following COVID-19 vaccination in children, adolescents, and young adults with cancer. Vaccines work by stimulating the body's immune cells to respond against a specific disease. The immune response produces protection from that disease. Read more about this study

About this study
Official title: Prospective Cohort Study to Evaluate Immunologic Response Following COVID-19 Vaccination in Children, Adolescents and Young Adults With Cancer
This study evaluates immunologic response following COVID-19 vaccination in children, adolescents, and young adults with cancer. Vaccines work by stimulating the body's immune cells to respond against a specific disease. The immune response produces protection from that disease. Effects from cancer and from treatments for cancer can reduce the body's natural disease fighting ability (called immunity). Factors such as vaccine type, timing of vaccine dosing related to treatment for cancer and number of vaccine doses or "boosts" (extra vaccine shots) may strengthen or diminish the body's protective immune response. This study may help researchers learn more about how the body's immune system responds to the COVID-19 vaccine when the vaccination is given during or after cancer treatment.
Read the detailed description
PRIMARY OBJECTIVE:
- Characterize the immunologic response following severe acute respiratory syndrome (SARS)-coronavirus (CoV)-2 vaccination in children, adolescents, and young adults with cancer who are currently receiving or who recently completed treatment with immunosuppressive therapy.
EXPLORATORY OBJECTIVES:
- Describe the rate of post-vaccination symptomatic SARS-CoV-2 infections. II. Assess the durability of immune response to SARS-CoV-2 vaccine over 2 years.
III. Describe the longer-term impacts of vaccine immune response including subsequent COVID-19-related serious illness.
IV. To help guide future vaccine dosing and timing, at each SARS-CoV-2 vaccine dose administration determine the degree of:
IVa. Lymphopenia (absolute lymphocyte count cells/mm^3); IVb. Helper T-cell suppression (CD4 count); IVc. B-cell suppression (CD19 count). V. Provide a mechanism for data collection and banking of biospecimens for use in research regarding immune response to SARS-CoV-2 vaccination.
OUTLINE:
Patients receive COVID-19 vaccine per standard of care. Patients also complete a survey at 1 month and undergo collection of blood samples at 1, 3, 6, 12, 18, and 24 months. Patients may complete an additional survey at 1 month after each vaccine boost and undergo collection of blood samples before each vaccine boost, 1 month after each vaccine boost, and at the time of COVID-19 infection.

What is being measured
The primary outcome is the main question the study is designed to answer.
Seroprevalence of SARS-CoV-2-specific protective antibodies
Will report the proportion of patients with a serologic response to a protocol-approved COVID-19 vaccine, captured using a test for SARS-CoV-2-specific antibodies via immunoassay, and will report a corresponding 95% confidence interval.
Measured: 24 months following initial vaccination with a protocol-approved COVID-19 vaccine
