Study Summary

Antibodies are an important part of the body's defense against infection. Individuals who have no antibodies or very low antibody levels are considered less well protected from Coronavirus Disease 2019 (COVID-19) than those who have higher antibody levels. What level of antibodies is necessary for protection is currently unknown. Inadequate antibody response to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccination has been described among kidney transplant recipients. The aim of this study is to elicit an antibody response to vaccination against SARS-CoV-2 in kidney transplant recipients who have failed to respond to two doses of either the Moderna COVID-19 vaccine or Pfizer-BioNTech Coronavirus Disease 2019 (COVID-19) vaccine.

Primary Outcome

The proportion of participants who achieve an antibody response \>50 U/mL after the third dose of vaccine using the Roche Elecsys® anti-RBD assay is considered to show positive response to the intervention, negative response otherwise.

Interventions

  • BIOLOGICAL BNT162b2 vaccine (Pfizer/BioNTech)
  • BIOLOGICAL mRNA-1273 vaccine (Moderna)
