n = Number of patients on hemodialysis used in each study for determining seroconversion rates

Seroconversion rates are reported as percentage of patients for whom anti-spike protein antibodies were measured above a predetermined positive threshold by each individual study

*Interval between last dose given and measurement of seroconversion rate
