IMPACT OF KIDNEY FAILURE ON THE REGULATION OF HUMORAL RESPONSE TO VACCINATION

Not yet recruiting
Conditions
Chronic Kidney Disease Requiring Chronic Dialysis
Vaccine Response
Interventions
Biological: Influenza vaccination
Registration Number
NCT06635525
Lead Sponsor
Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico
Brief Summary

The aim of this observational study is to determine if and how kidney failure affects the development of protective immune responses following vaccination in patients on chronic dialysis.

Researchers will compare the effectiveness of the influenza vaccine in inducing protective antibodies between hemodialysis patients and subjects without chronic kidney disease.

Participants will:

* Be enrolled at the time of influenza vaccination

* Visit the clinic at 7, 14, 30, 60, and 120 days after vaccination

* Be asked to provide relevant clinical information and a blood sample at each visit
