甲，乙肝疫苗终身只需注射１次吗？ 我儿子２岁时注射过甲，乙肝疫苗 （３针），现在８岁要回中国１个月。还需要注射甲，乙肝疫苗吗？

要，都要

Thanks. Do you know how long is the hepatitis A and B vaccine (for example Twinrix) good for after the shot? few months or few years?

别听别人乱讲, 打过3针, 一辈子不用再打了, 你也可以去问问医生

那种疫苗应该是终生免疫的吧，我问过我儿子的医生，医生说是打过一次就不用再打了．你也可以再问问你孩子的医生．

甲肝的打一次就可以，乙肝不一定，有人打了3次都不会产生抗体，要重头打。就算产生抗体后，时间长了，抗体也会消失，这时候也要重头打3针。如果在还有抗体的时候，隔一段时候打个加强针，能刺激抗体的产生。

Thank you all. I will check with my family doctor. It seems my son need to do a blood test to see if my son still has the 抗体.

我的医生说要打4针可以终身免疫，乙肝。甲肝好像没这么长。
