Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Study subjects requiring primary hepatitis B vaccination schedule were randomized to receive either four doses of 20mcg intramuscularly or four doses of 40mcg intramuscularly, at 0, 1, 2 and 6 months.

CKD patients and patients on dialysis who had previously completed primary hepatitis B vaccination schedule but required booster hepatitis B vaccination received a single dose of 40mcg intramuscularly. Healthy controls who had previously completed primary hepatitis B vaccination schedule but required booster hepatitis B vaccination received a single dose of 20mcg intramuscularly.

All study participants who required seasonal influenza vaccine received 0.5ml of vaccine intramuscularly. For patients who received both hepatitis B vaccine (either first dose of primary schedule or booster vaccine) and influenza vaccine, they were administered more than 4 weeks apart.

All vaccines were considered "one-off" events for recruitment. Repeated vaccinations eg. with seasonal influenza vaccine annually, was not specifically studied.
