Analysis of the Specificity and Persistence of Nasal Immune Responses to Respiratory Viral Antigens in Immunocompromised and Healthy Cohorts

Sponsor: Fondazione IRCCS Policlinico San Matteo di Pavia

Summary

The goal of this observational study is to characterize nasal mucosal immunity to respiratory viruses, such as SARS-CoV-2, in immunocompromised individuals and healthy volunteers. The study involves adults of any sex, between 18 and 90 years old, including both immunocompromised patients with medical conditions or treatments that can affect immune cell functions and healthy controls with no underlying medical conditions declared, no clinical history of immunodeficiency or use of immunosuppressive medications. Researchers will compare immunocompromised participants to healthy volunteers to determine how underlying immunodeficiency and related treatments affect immune cell composition and virus-specific responses.
