To investigate the situation of internal antibody positive rate of Chinese who exposed to rabies virus and received full procedure of rabies vaccination, and to provide the basis for the adjustment of rabies vaccination procedure and policy. Methods We electronically searched databases including WanFang Data, VIP, CNKI, PubMed and EMbase from inception to May 2015 to collect studies about Chinese exposed to rabies virus and received full procedure rabies vaccination. Two reviewers independently screened literature, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using R software (R3.2.1). Results A total of 33 studies were included. The combined antibody positive rate was 93.99% with 95%CI 92.02% to 95.70%. Antibody positive rate among male was 93.73% with 95%CI 91.65% to 95.54%, while among female was 94.33% with 95%CI 92.35% to 96.04%, and there was no significant difference between male and female (P>0.05). The antibody positive rate of hamster kidney cell rabies vaccine was 89.94% with 95%CI 86.09% to 95%, while the antibody positive rate of vero cell rabies vaccine was 96.65% with 95%CI 94.99% to 94.99%, and there was significant difference between both groups (P<0.05). There was no statistical difference in antibody positive rates among different years of rabies vaccine (P>0.05). However, the antibody positive rate of rabies vaccine had a tendency to reduce with the increasing age Conclusion Antibody positive rate of vero cell rabies vaccine is higher than that of hamster kidney cell rabies vaccine. Older people have lower antibody positive rate after receiving rabies vaccination. We suggest using vero cell rabies vaccine when giving rabies vaccination; elderly people should receive booster vaccination after basic vaccination.
