Aim: To assess the immunogenicity and safety of rabies vaccination under the Zagreb and Essen regimens by performing a meta-analysis. Methods: Electronic databases were searched for eligible studies. Risk ratios and weighted mean differences with 95% CIs were used to calculate estimates. Results: A total of 18 studies were included. Rabies virus neutralizing antibody concentration was comparable between the two regimens at D7 and 14. No significant differences were observed in seroconversion rates from D14 and 42. Incidence of fever was higher in Zagreb group (risk ratio: 1.55 [1.37-1.76]); but no significant differences were present for other common adverse events. Conclusion: Rabies vaccination under the Zagreb regimen was noninferior to the Essen regimen in immunogenicity and had an acceptable safety profile.
