目的:分析水痘疫苗对水痘发病率和病情的作用。方法:选取2013年11月到2014年11月到我院进行水痘治疗患者110例作为研究的对象,其中有60例患者有过水痘疫苗接种史,有50例患者未有过水痘疫苗接种史。分析他们水痘疫苗发生率和具体病情,做好详细记录。结果:在55例有过水痘疫苗接种史患者中,有5例属于重型,其余55例均为轻型,轻型发生率为90.9%。在55例未有过水痘疫苗接种史患者中,有9例属于重型,其余均46例均为轻型,轻型发生率为83.6%。在轻型发生率中,组间数据对比有差异,具有统计学意义(P<0.05)。在接种水痘疫苗一年的时间里,发生水痘的为5例,在接种五年内,发生水痘的为36例。结论:有过水痘疫苗接种史的患者,病情轻型的发生率明显要高于未有过水痘疫苗接种史患者,水痘疫苗可以有效的控制水痘发病率。建议所有的儿童都应该接种水痘疫苗。 Objective: To analyze the effect of varicella vaccine on the incidence and severity of chickenpox. Methods: A total of 110 cases of chickenpox treated in our hospital from November 2013 to November 2014 were selected as the study subjects. Among them, 60 cases had history of varicella vaccination and 50 cases had no history of varicella vaccination. Analysis of their incidence of varicella vaccine and the specific conditions, make a detailed record. Results: Of the 55 patients who had had varicella vaccination, 5 were severe and the other 55 were light and light with a 90.9% incidence. Of the 55 patients who did not have a history of varicella vaccination, 9 were heavy and the remaining 46 were light and 83.6%, respectively. In the light incidence, there was a significant difference between the groups in the data, with statistical significance (P <0.05). Five years after the chickenpox vaccine was administered, there were 5 cases of chickenpox and 36 cases of chickenpox within five years of vaccination. CONCLUSIONS: Patients with a history of varicella vaccination have a significantly higher incidence of mild disease than those who have never had a history of varicella vaccination, and varicella vaccines can effectively control the incidence of chickenpox. It is recommended that all children should receive a chickenpox vaccine.
