据Medical Tribune1992年3月报道:美国疾病控制中心建议,凡是符合接种乙型肝炎疫苗条件的幼儿都要给予接种。该中心负责肝炎问题的Harold Margolis博士说,从1981年起,该中心就建议婴幼儿应接种三次乙型肝炎疫苗,第一次应在婴儿出生后尽早接种,后两次则可与其它疫苗一起接种。Margolis认为,接种的效果15年后将可以看出,那时大概就不会再有人感染乙型肝炎病毒。 1979年以来,美国每年新增加的乙型肝炎感染者就达25～30万人。该中心尽管没有正式劝告年岁大的儿童接种乙型肝炎疫苗,但Margolis认为,最好也能接种疫苗。根据该中心的劝告,美国一些州已将学龄前儿童接种乙型肝炎疫苗作为一项义务来实施。另外一些州也正在研究

Margolis believes that the effects of vaccination will be 15 years from now, and probably no one will be infected with the hepatitis B virus at that time. Since 1979, there have been between 250 and 300,000 new hepatitis B infections newly added to the United States each year. Although the center did not formally advise older children on hepatitis B vaccination, Margolis believes it is best to get vaccinated. According to the center’s advice, some states in the United States have already implemented preschool children’s vaccination against hepatitis B as an obligation. Other states are also studying
