COVID-19 Vaccine Boosters in Patients With CKD

A Multi-Centre 12 Month Parallel-Group Randomized Control Trial of BNT162b2 Versus mRNA( Messenger Ribonucleic Acid) -1273 COVID-19 Vaccine Boosters in Chronic Kidney Disease and Dialysis Patients With Poor Humoral Response Following COVID-19 ( Corona Virus Disease of 2019)Vaccination

This study is a 12-month, four-arm parallel-group randomized control trial of Pfizer-BioNTech versus MODERNA COVID-19 (Corona Virus disease 2019)vaccine boosters in chronic kidney disease and dialysis patients with poor humoral response following COVID-19 vaccination, in collaboration with 5 dialysis centers in Ontario and British Columbia, Canada .

Patients will be randomized to MODERNA or Pfizer-BioNTech COVID-19 vaccine, they may have received either MODERNA or Pfizer-BioNTech COVID-19 vaccine for their initial two doses of vaccine, and will be stratified by their initial vaccine type (MODERNA or Pfizer-BioNTech ) prior to randomization, which will result in four study groups.

MODERNA : Nucleocapsid Modified messenger RNA BioNTech: Bio-Pharma new Technology
