Outcome Measures

Primary Outcomes (1)

  • Humoral immune response in kidney transplant recipients following anti-SARS-CoV2 mRNA vaccination.

    anti-spike SARS-CoV-2 IgG measured ≥15 days after vaccination

    15 days-90 days

Secondary Outcomes (5)

  • Humoral immune response in kidney transplant recipients following anti-SARS-CoV2 mRNA vaccination.

    3 months - 6 months

  • Cellular immune response in kidney transplant recipients following anti-SARS-CoV2 mRNA vaccination.

    15 - 90 days

  • Graft function after vaccination

    15 days-90 days

  • Clinical variables affecting antibody levels

    15 days-90 days

  • The impact of frailty syndrom on humoral response in older kidney recipients (70+ years of age) following anti-SARS-CoV-2 mRNA vaccination

    15 days-90 days

Study Arms (3)

SARS-CoV-2 naive

Kidney transplant recipients without previous SARS-CoV-2 infection verified by absence of RT-PCR test in national database who receive SARS-CoV-2 mRNA vaccine after transplantation.

Diagnostic Test: anti-spike SARS-CoV-2 IgG

SARS-Cov-2 exposed

Kidney transplant recipients with previous SARS-CoV-2 exposition verified by positivity of RT-PCR test in national database who receive SARS-CoV-2 mRNA vaccine after transplantation.

Diagnostic Test: anti-spike SARS-CoV-2 IgG

Waiting list

Kidney transplant recipients who were vaccinated on waiting list (a) SARS-CoV-2 naive (b) SARS-Cov-2 exposed

Diagnostic Test: anti-spike SARS-CoV-2 IgG

Interventions

Immunochemiluminescent assay by DiaSorin S.p.A. Italy
