本文对两组新生儿分别注射冰箱保存和室温保存的乙肝疫苗,并进行效果观察。结果注射冷藏疫苗组免后抗-HBs 阳转率为81.9%(190/232);室温疫苗组免后抗-HBs 阳转率为81.6%(292/358)。两组抗体阳转率十分接近(X~2=0.072,p>0.5)。认为乙肝疫苗在无冷藏条件的地区,特别是缺电的农村地区可存放室温保存3个月效价不减。
In this paper, two groups of neonates were injected into the refrigerator and stored at room temperature, hepatitis B vaccine, and the effect was observed. Results The anti-HBs positive rate was 81.9% (190/232) in the refrigerated vaccine group and 81.6% (292/358) in the anti-HBs vaccine group. Antibody positive rate of two groups is very close (X ~ 2 = 0.072, p> 0.5). Hepatitis B vaccine in cold-free areas, especially in rural areas can be stored at room temperature for three months to keep the titer unabated.
