Summary
Brief summary
This is an observational cohort study assessing the serological response to COVID-19 vaccination in kidney and kidney pancreas transplant recipients and patients treated with maintenance dialysis at Auckland City Hospital. Three analyses will be undertaken:
1. Vaccine immunogenicity based on humoral and cellular responses. Serological testing for the antibody to SARS-CoV-2 will be done prior to vaccination and again at 1 and 3 weeks and 6 months after the booster vaccination in dialysis and transplant recipients. Cellular responses will be assessed at 3 weeks after the booster vaccination.
2. Development of anti-HLA antibodies in dialysis patients on the kidney transplant waiting list in the first 12 months after vaccination.
3. Development of acute rejection episodes at 1, 4, 8 and 12 weeks after vaccination in recipients of kidney and kidney-pancreas transplants.
