Brief summary
An open label, non-randomized pilot study in kidney transplant recipients who received a completed primary series and bivalent booster of mRNA based COVID-19 vaccine and have ≤2500 U/mL SARS-CoV-2 S antibody concentration using the Roche Elecsys(R) anti-RBD assay. Up to 80 participants will be enrolled in this study. Eligible participants will receive a dose of the Sanofi-GSK monovalent (B.1.351) CoV2 preS dTM-AS03 COVID-19 vaccine candidate.. The primary objective is to determine whether a booster dose of the Sanofi-GSK monovalent (B.1.351) CoV2 preS dTM-AS03 COVID-19 vaccine will elicit an increased SARS-CoV-2 antibody response in participants who have failed to maintain an antibody titer \>2500 U/mL (using the Roche Elecsys(R) anti-RBD assay) to 2 or more doses of mRNA based COVID-19 vaccine
Interventions
0.5 mL per dose of the Sanofi-GSK COVID-19 Vaccine will be administered intramuscularly in the deltoid muscle of the upper arm

Outcome results
The Proportion of Participants Who Reach a SARS-CoV-2 S Antibody Level >5000 U/mL
The antibody is measured by using the Roche Elecsys(R) anti-RBD assay
