| 目的 比较流感亚单位疫苗与裂解疫苗的安全性和免疫原性.方法 流感亚单位疫苗和裂解疫苗按随机双盲法分别接种249名和250名6～12岁健康儿童.于接种当日和接种后3天内观察局部反应和全身反应.用血凝抑制试验检测接种儿童免疫前后的血凝抑制抗体(HI)滴度,计算抗体4倍增长阳转率,免疫后的保护水平抗体(≥1∶40)的免疫成功率,以及抗体几何平均滴度(GMT)值和增长倍数.比较流感亚单位疫苗和裂解疫苗的临床观察结果.结果 两种疫苗接种后均未见局部反应,发热反应率和中高度发热反应率亚单位疫苗低于裂解疫苗,两组的差异有显著的统计学意义.未见其他全身反应.对疫苗 3个毒株的血清学检测结果显示:亚单位疫苗的阳转率为74.5%～95.1%,保护水平抗体的免疫成功率为94.2 %～99.6%,抗体GMT增长倍数为5.4～21.2.裂解疫苗的阳转率79.8%～97.8%,保护水平抗体的免疫成功率为96.4%～100.0%,抗体GMT增长倍数6.4～21.0.两种疫苗的免疫学效果相似,所见差异无显的统计学意义.结论 流感亚单位疫苗和裂解疫苗接种6～12岁儿童后反应轻微,安全性良好,亚单位疫苗发热反应率低于裂解疫苗.两种疫苗的免疫原性良好,具有同样显著的免疫效果,可以推广使用. |

| Objective To compare the reactogenicity and serology between influenza subunit vaccine and split vaccine.Methods A rand-omized double-blind study was carried out among children(age 6一12year) in order to compare the safety and immunogenicity of an infl-uenza inactivated subunit vaccine(Agrippal,Chiron Vaccines) with that of a split vaccine(Flurix,GSK).ResultsA total of 499 subj-ects were vaccinated and included in the safety analysis.A total of 249 subjects received Agrippal and 250 received Flurix.All subj-ects were kept under medical observation for 30 minutes in order to check the evidence of having any immediate local and systemic reac-tion. Daily observation records were collected during the 3-day follow-up after vaccination. 6.4%of the cases with fever≥37.5 ℃ was reported in the Flurix group but 2.4%in Agrippal group which was significantly less than the former group(P>0.05). Blood samples(the DO pre- and D23 post-vaccination sera) were collected from 224 of Agrippal group and 223 of Flurix group and analysed by the haemaggluti-nation inhibition(HI)assay. Agrippal and Flurix induced similar seroprotection(HI titerv1:40， HINT 99.6% vs 100.0%;H3N2 99.1%。99.1%)
and seroconversion(4-fold increase 95.1% vs 97.8%;H3N2 74.5% vs 79.8%)rates and geometric mean titer(GMT)increase(16.0 vs 21.0) 5.4 vs 6.4)against the two A subtypes. A similarseroprotection rate(94.2% vs 96.4%)and GMT increase(21.2 vs 18. 2) against the i-nfluenza B strain were also noticed in both vaccines. No significant difference was found in the results of immunological assay between the two vaccines(P<0.05).A lower seroconversion rate against B strain was observed in Agrippal group than in Flurix group (91.1%vs 97.3%). Conclusion In terms of safety both vaccines were generally well tolerated.The fever reaction was less frequently seen in the Agri-ppal group.Both vaccines induced an effective immune response in the vaccines. |
