PRIMARY outcome

Timeframe: Outcome was measured at 30 days after study intervention (dose 3 vaccination)

Population: All individuals who receive the intervention and have antibody response measured at 30 days after the intervention will be included in the analysis of the primary outcome. For secondary and exploratory outcomes, all individuals who receive the intervention and have that outcome measured will be included.

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.
