Background It has been hypothesized that revaccination with live vaccines is associated with reductions in off-target morbidity and mortality. We examined if revaccination with the live measles, mumps, and rubella vaccine (MMR) is associated with a lower rate of off-target infections. Methods We performed a register-based nationwide cohort study that included 295559 children born in Denmark from April 2004 to December 2010. The cohort were followed from age 47 months (1 month before turning age 4 years, which is the recommended age of the second MMR [MMR-2]) until age 60 months. In Cox regression, we estimated adjusted incidence rate ratios (aIRRs) of antibiotic prescriptions and hospital admissions for any infection comparing MMR-2 as most recent vaccine with not having MMR-2 as the most recent vaccine. Results There was no association between MMR-2 and antibiotic prescriptions (aIRR, 1.01; 95% confidence interval [CI], 0.99-1.02). The aIRR for the association between MMR-2 and admissions for infection of any duration was 0.93 (95% CI, 0.88-0.98). For admissions for infection lasting 0 to 1 day, the aIRR was 0.97 (95% CI, 0.90-1.03) compared with the aIRR of 0.84 (95% CI, 0.74-0.95) for admissions for infection lasting 2 days or longer (test for equality of aIRRs, P = .039). Conclusions In this study, revaccination with MMR appeared safe in relation to off-target infections and was associated with a lower rate of severe off-target infections. More studies of the possible association between revaccination with live attenuated vaccines and off-target infections are needed.

麻疹-腮腺炎-风疹疫苗的再接种和传染病发病率:基于丹麦登记的队列研究。

背景已经假设活疫苗的再接种与脱靶发病率和死亡率的降低有关。我们检查了活麻疹,腮腺炎和风疹疫苗(MMR)的再接种是否与较低的脱靶感染率相关。方法我们对2004年4月至2010年12月在丹麦出生的295559名儿童进行了基于登记册的全国队列研究。该队列从47个月(4岁之前的1个月)开始随访,这是第二次MMR的推荐年龄[MMR-2])直到60个月大。在Cox回归中,我们比较了将MMR-2作为最新疫苗而没有将MMR-2作为最新疫苗的情况,估计了针对任何感染的抗生素处方和住院治疗的调整后发生率(aIRRs)。结果MMR-2与抗生素处方之间没有关联(aIRR,1.01; 95%置信区间[CI],0.99-1.02)。MMR-2和任何时间的感染入院之间的相关性的aIRR为0.93(95%CI,0.88-0.98)。对于持续0到1天的感染入院,aIRR为0.97(95%CI,0.90-1.03),而对于持续2天或更长时间的感染入院,aIRR为0.84(95%CI,0.74-0.95)(测试aIRR相等,P = .039)。结论在这项研究中,MMR的再接种对于脱靶感染似乎是安全的,并且与严重的脱靶感染率较低相关。需要对减毒活疫苗的重新接种与脱靶感染之间的可能关联进行更多研究。95%置信区间[CI],0.99-1.02)。MMR-2和任何时间的感染入院之间的相关性的aIRR为0.93(95%CI,0.88-0.98)。对于持续0到1天的感染入院,aIRR为0.97(95%CI,0.90-1.03),而对于持续2天或更长时间的感染入院,aIRR为0.84(95%CI,0.74-0.95) aIRR相等,P = .039)。结论在这项研究中,MMR的再接种对于脱靶感染似乎是安全的,并且与严重的脱靶感染率较低相关。还需要对减毒活疫苗的重新接种与脱靶感染之间的可能联系进行更多研究。95%置信区间[CI],0.99-1.02)。MMR-2和任何时间的感染入院之间的相关性的aIRR为0.93(95%CI,0.88-0.98)。对于持续0到1天的感染入院,aIRR为0.97(95%CI,0.90-1.03),而对于持续2天或更长时间的感染入院,aIRR为0.84(95%CI,0.74-0.95)(测试aIRR相等,P = .039)。结论在这项研究中,MMR的再接种对于脱靶感染似乎是安全的,并且与严重的脱靶感染率较低相关。还需要对减毒活疫苗的重新接种与脱靶感染之间的可能联系进行更多研究。对于持续0到1天的感染入院,aIRR为0.97(95%CI,0.90-1.03),而对于持续2天或更长时间的感染入院,aIRR为0.84(95%CI,0.74-0.95)(测试aIRR相等,P = .039)。结论在这项研究中,MMR的再接种对于脱靶感染似乎是安全的,并且与严重的脱靶感染率较低相关。还需要对减毒活疫苗的重新接种与脱靶感染之间的可能联系进行更多研究。对于持续0到1天的感染入院,aIRR为0.97(95%CI,0.90-1.03),而对于持续2天或更长时间的感染入院,aIRR为0.84(95%CI,0.74-0.95) aIRR相等,P = .039)。结论在这项研究中,MMR的再接种对于脱靶感染似乎是安全的,并且与严重的脱靶感染率较低相关。还需要对减毒活疫苗的重新接种与脱靶感染之间的可能联系进行更多研究。用MMR再次疫苗接种对于脱靶感染似乎是安全的,并且与严重的脱靶感染率较低相关。还需要对减毒活疫苗的重新接种与脱靶感染之间的可能联系进行更多研究。用MMR再次疫苗接种对于脱靶感染似乎是安全的,并且与严重的脱靶感染率较低相关。还需要对减毒活疫苗的重新接种与脱靶感染之间的可能联系进行更多研究。
