乙肝基因工程(CHO)疫苗的免疫效果介绍
乙肝基因工程疫苗自1992年获得生产文号投入大量生产以来，免疫接种后安全可靠。血清学效果优于血源乙肝疫苗。两种疫苗可以互相使用。对以前曾经用过血源疫苗未完成全程免疫的儿童，再用乙肝基因工程疫苗补充全程或加强免疫，同样可以获得满意效果。

简述乙肝基因工程(CHO)疫苗的副作用
自1979年乙肝疫苗问世以来，经过20多年大规模的使用和观察，目前还没有接种乙肝疫苗后有严重副作用的病例。只有少数人接种后会产生接种部位红肿、疼痛、发痒、手臂酸重等症状，或者是产生低热、乏力、恶心、食欲不振等与一般疫苗相似的轻微反应，这些症状即使不做任何处理，一般在3天以内也会自动消失 [1]
乙肝基因工程(CHO)疫苗的注意事项
(1)安瓿破裂、疫苗变质或有摇不散的块状物，不得使用。 (2)疫苗注射前要充分摇匀。 (3)接种疫苗时认明10ug/支及20μg/支两种规格。 乙肝基因工程疫苗应于2-8℃条件下贮运，严防冻结，疫苗有效期为2年。
