Meta-analysis of safety of human purified Vero cell rabies vaccine after exposure / 中国生物制品学杂志

ABSTRACT

@#Objective To evaluate the safety of human purified Vero cell rabies vaccine(PVRV)after exposure in China by Meta-analysis.Methods With rabies,vaccine and safety as key words,a systematic search was performed in PubMed,EMBASE,Cochrane and China National Knowledge Infrastructure(CNKI),supplemented by manual retrieval.A Meta-analysis was performed to analyze the incidence of adverse events of two immunization regimens Zagreb and Essen using Review Manager 5.4 software after literature screening and data extraction according to the inclusion and exclusion criteria.Results A total of 12 studies were included,of which 7 were prospective studies and 5 were retrospective studies.Most included in the studies showed a low risk of bias.The incidence of adverse events in Zagreb regimen was significantly higher than that in Essen regimen[relative risk(RR)= 1.01,95% CI = 0.90 ～ 1.14;I2= 73.00%,P<0.05],but there was a high degree of heterogeneity.The incidence of fever,pain and induration in Zagreb regimen was significantly higher than that in Essen regimen(RR = 1.14,0.92 and 0.86,95% CI = 0.82 ～ 1.60,0.73 ～ 1.14 and 0.29 ～ 2.51;I2= 73.00%,P<0.05],but there was a high degree of heterogeneity.The incidence of fever,pain and induration in Zagreb regimen was significantly higher than that in Essen regimen(RR = 1.14,0.92 and 0.86,95% CI = 0.82 ～ 1.60,0.73 ～ 1.14 and 0.29 ～ 2.51;I2= 81%,65% and 92%,respectively,P<0.01).Conclusion Two regimens of PVRV vaccination after exposure showed good safety.However,when adopting Zagreb regimen,attention should be paid to the physical conditions of children and the elderly with relatively poor immunity to avoid adverse events.
