	Antiurease IgG secreting cells positive/total volunteers*	Antiurease IgG peak ASC median† (range) [day to peak]	Antiurease IgA secreting cells positive/total volunteers*	Antiurease IgA peak ASC median† (range) [day to peak]
*Positive status defined as ≥15 urease specific ASC/10⁶ peripheral blood lymphocytes. †Highest count of urease specific ASC/10⁶ peripheral blood lymphocytes between day 7 and day 73. Positive results only.
