Within the limits of current assay variability, the 50U dose of VAQTA contains less than 0.
Protection after vaccination with VAQTA has been associated with the onset of seroconversion ((>=)10 mIU/mL of hepatitis A antibody, measured by a modification of the HAVAB** radioimmunoassay (RIA)(2)) and with an anamnestic antibody response following booster vaccination with VAQTA.
A very high degree of protection has been demonstrated after a single dose of VAQTA in children and adolescents.
In subjects who were initially seronegative, the protective efficacy of a single dose of VAQTA was observed to be 100% with 21 cases of clinically confirmed hepatitis A occurring in the placebo group and none in the vaccine group (p<0.
Although cases of imported infection have occurred, the study community has remained free of outbreaks, evidence for the effectiveness of VAQTA for use in community outbreak control.
The efficacy of VAQTA in other age groups was based upon immunogenicity measured 4 to 6 weeks following vaccination.
In initially seronegative children 12 through 23 months of age, who received VAQTA with or without other vaccines, 96% (n=471; 95% CI: 93.
In combined clinical studies in adults 19 years of age and older who received VAQTA (50 U/1.
In subjects who received VAQTA at 0 and 6 months, the GMT was 819 mIU/mL (n=175) at 2.
In adults that were administered VAQTA at 0 and 6 months, the hepatitis A antibody response to date has been shown to persist up to 6 years in adults.
The total duration of the protective effect of VAQTA in healthy vaccinees is unknown at present.
50U) of VAQTA, 4 weeks after the booster dose was administered at 6, 12, and 18 months after the first dose, 100% of 1201 subjects, 98% of 91 subjects, and 100% of 84 subjects were seropositive, respectively.
