This observational retrospective study aims at verifying hepatitis-B-virus (HBV) vaccination coverage in students vaccinated before and after 1992, in order to optimize health surveillance and vaccination recall.
Vaccination status was evaluated using the anti-HBs antibody titer (anti-HBs). Student t-test and the chi-square test were performed to identify the average age and the difference in antibody coverage between the two genders and in the two populations analyzed.
Our study outlined a prevalence of 21.83% uncovered trainees among those vaccinated at age 12 and 45.03% among those vaccinated in neonatal age.
In conclusion, our data showed persistent protection against HBV infection in healthcare students.
本观察性回顾性研究旨在验证 1992 年前后接种乙型肝炎病毒(HBV)疫苗的学生的疫苗接种率,以优化健康监测和疫苗接种召回。
使用抗-HBs 抗体滴度(抗-HBs)评估疫苗接种状态。采用学生 t 检验和卡方检验比较两种人群中男女之间及两种疫苗接种年龄组之间的平均年龄和抗体覆盖率差异。
本研究发现,12 岁时接种疫苗的人群中有 21.83%未接种疫苗,而新生儿时期接种疫苗的人群中有 45.03%未接种疫苗。
综上所述,我们的数据表明,医疗保健专业学生对 HBV 感染具有持续的保护作用。
