摘要 目的 分析一种国产冻干人二倍体细胞狂犬病疫苗(Human diploid cell based rabies vaccine, RabV-hdc)预防接种不良事件发生率及其影响因素。方法 选择2018年6月至2020年9月在陕西省13个区县狂犬病暴露预防处置门诊接种RabV-hdc的受试者,观察每剂次接种后0-3d发生的不良事件,分析不良事件发生率和影响因素。结果 共入组31 623例受试者,累计接种148 851剂次RabV-hdc,发生不良事件352例次,总发生率为2.36‰。局部、全身不良事件发生率分别为1.38‰、1.06‰;1级、2级、3级、4级不良事件发生率分别为0.95‰、1.13‰、0.28‰、0.00‰。多因素Logistic回归分析显示,女性受试者不良事件发生率高于男性受试者,0-4岁、5-14岁受试者高于≥60岁受试者,免疫机能低下或过敏体质受试者高于其他受试者,Ⅲ级暴露受试者高于Ⅰ/Ⅱ级暴露受试者[OR(95%CI):1.51(1.19-1.92)、6.49(2.85-14.79)、2.69(1.17-6.20)、6.09(2.64-14.04)和1.81(1.30-2.51)]。结论 本研究RabV-hdc接种后不良事件发生率在预期范围内,以女性、0-14岁人群、免疫机能低下或过敏体质人群和暴露等级Ⅲ级者发生风险高;建议加强RabV-hdc接种后护理。 Objective To explore the incidence of adverse events following immunization with a domestic human diploid cell-based rabies vaccine(RabV-hdc) and its influencing factors.Methods We enrolled individuals with suspected rabies exposure from clinics in 13 districts/counties of Shaanxi province from June 2018 to September 2020 and vaccinated them with RabV-hdc. We observed for adverse events 0-3 days after each dose to determine the incidence and its influencing factors.Results A total of 31 623 subjects were enrolled, and 148 851 doses of RabV-hdc were administered. Adverse events occurred following 352 vaccine doses, for an incidence of 2.36‰. Incidences for local and systemic adverse events were 1.38‰ and 1.06‰;and for grade 1, 2, 3, and 4 adverse events were 0.95‰, 1.13‰, 0.28‰, and 0.00‰, respectively. Multivariate logistic regression showed that the incidence of adverse event was higher among females than males, among 0-4-and 5-14-year-olds than among ≥60-year-olds, among low-immunity or allergic individuals than among others, and among subjects with level Ⅲ exposures than among subjects with level Ⅰ/Ⅱ exposures, respectively [OR(95%CI): 1.51(1.19-1.92), 6.49(2.85-14.79), 2.69(1.17-6.20), 6.09(2.64-14.04), and 1.81(1.30-2.51)].Conclusions The overall incidence of RabV-hdc adverse events was acceptable, and was higher among females, 0-14-year-olds, low-immunity or allergic individuals, and individuals with level Ⅲ exposures. We suggest strengthening post-vaccination healthcare.
