目的了解平塘县卡蒲毛南族、汉族、布依族、苗族新生儿乙肝疫苗免疫成功率状况。方法对完成全程乙肝疫苗免疫后的132名婴幼儿采集静脉血分离血清,检测乙肝病毒表面抗体(抗-HBs)。结果平塘县新生儿乙肝疫苗免疫成功率为74.24%,不同民族新生儿乙肝疫苗免疫成功率比较,差异有统计学意义(χ~2=14.18,P<0.01);HBV感染率为0;不同性别新生儿乙肝疫苗免疫成功率比较,差异无统计学意义(χ~2=0.00,P>0.05)。结论加强基层医务人员预防接种技术培训,规范操作,加强疫苗冷链管理,提高有效接种率,是控制乙型肝炎的关键。
Objective To understand the success rate of Hepatitis B vaccine immunization of card Pumaonan, Han, Buyi and Miao neonates in Pingtang County. Methods Blood samples were collected from 132 infants who had completed the whole-dose hepatitis B vaccine immunization to detect hepatitis B virus surface antigens (anti-HBs). Results The success rate of Hepatitis B vaccine immunization was 74.24% in Pingtang County, and the difference was statistically significant (χ ~ 2 = 14.18, P <0.01). The HBV infection rate was different between different ethnic groups There was no significant difference in the success rate of hepatitis B vaccination among sex neonates (χ ~ 2 = 0.00, P> 0.05). Conclusion It is the key to control hepatitis B that it is necessary to strengthen training on vaccination of grassroots medical staff, standardize operation, strengthen cold chain management of vaccines and increase effective vaccination rate.
