Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is to investigate the humoral immune response to COVID-19 vaccines in haematological patients, by testing SARS-CoV-2 seroconversion

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This single-center prospective study will enroll approximately 700 hematologic patients who access to Haematological Division (San Gerardo Hospital, Monza, Italy) in order to perform their routine blood tests to monitor their hematological conditions. Evaluation of Sars-Cov-2 IgG specific antibodies will be performed on left-over biological material (serum or plasma) collected during routine blood tests run between 30 and 60 days after the administration of the second vaccine dose.

Furthermore, in each patient who has failed seroconversion (absence of specific antibodies for circulation), his cellular immune response will be assessed using an additional blood sample collected during routine blood tests.

These samples will be collected within 9 months of the completion of the vaccination series and will be used to evaluate the plasma INF-γ release using QuantiFERON SARS-CoV-2 test.
