Evaluation of Immunologic Response Following COVID-19 Vaccination in Children, Adolescents, and Young Adults With Cancer

Description

PRIMARY OBJECTIVE:

I. 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:

I. 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.
