血源性乙型肝炎疫苗已为人们所熟知,对预防乙型肝炎的感染起着决定性作用。预测将来世界上消灭乙型肝炎之唯一途径即依靠疫苗。血源性疫苗虽然来源较困难,但在近几年内国内最可实施的也就是这种疫苗。众多的流行病学调查结果表明,亚洲地区母婴传播率很高,日本早年有个估计,每年有15万婴儿,约有1万名婴儿要通过母婴传播变成携带者,如作全球性计算,每年出生的婴儿约有60万以上在1岁以内即变成携带者。这个数字是惊人的。但近几年来由于采取了乙肝疫苗及高效价免疫球蛋白(HBIG)的联合阻断,在日本1岁以内婴儿的乙肝感染率降至0.1%,有的地区为0.05%左右,显示了
Blood-borne hepatitis B vaccines are well known and play a decisive role in the prevention of hepatitis B infection. The only way to predict the future eradicating hepatitis B in the world is to rely on the vaccine. Although the source of blood-borne vaccine is more difficult, but in recent years the most implementable in China is the vaccine. Numerous epidemiological findings show that there is a high rate of mother-to-child transmission in Asia. In early years in Japan, there was an estimated 150,000 infants and about 10,000 infants transgendered through mother-to-child transmission, Calculated that about 600,000 babies born each year are within 1 year of age that become carriers. This figure is amazing. However, in recent years, due to the combination of hepatitis B vaccine and high-titer immunoglobulin (HBIG), the prevalence of hepatitis B infection in infants aged less than 1 year in Japan dropped to 0.1% and in some areas to about 0.05%
