Figure 2. Comparison of RVNA titers between purified vero cell rabies vaccine (PVRV) and purified chick embryo cell vaccine (PCECV) vaccinated under Essen (1-1-1-1-1) regimen, the patients with WHO category II animal exposure were aged <5 years (A), 5–18 years (B), 19–60 years (C), and>60 years (D).

Significant differences between two groups were found for 6-18-year old patients at day 45 (D45) (**p<0.01) and 19-60-year old patients at day 365 post-vaccination (*p<0.05). The data shown are the mean±95% confidence interval. Student t test was used for the statistical analysis.
