在国内的时候儿科医生说4年一次免疫程序，当然自身有抗体的除外，我家的6岁打得第2次（自费），因为她堂姐是携带者。可以供楼主参考。

象楼上所说的，国内疫苗几年后需要巩固。这里的疫苗却没有这个要求。

是啊，看看这个

. w" J* b$ Z( ?2 m7 i: X5 S  ^' r/ [1 }Duration of protectionIt is now believed that the hepatitis B vaccine provides indefinite protection. However, it was previously believed and suggested that the vaccination would only provide effective cover of between five and seven years,[17][18] but subsequently it has been appreciated that long-term immunity derives from immunological memory which outlasts the loss of antibody levels and hence subsequent testing and administration of booster doses is not required in successfully vaccinated immunocompetent individuals.[19][20] Hence with the passage of time and longer experience, protection has been shown for at least 25 years in those who showed an adequate initial response to the primary course of vaccinations,[21] and UK guidelines now suggest that for initial responders who require ongoing protection, such as for healthcare workers, only a single booster is advocated at 5 years.[10]
