Objective To analyze the interdiction effect of hepatitis B vertical transmission through hepatitis B vaccine(HBVac) combined with hepatitis B immunoglobin(HBIG) by Meta analysis.Method Using fix effect model,9 randomization control trials are reanalyzed by Meta analysis.Results The OR values of single study ranged from 0.11 to 1.12.The OR value of Meta analysis was 0.46 and 95% confidence interval 0.2~0.67.Conclusion The combination of HBVac and HBIG interdicts hepatitis B vertical transmission better than single one.
