这是一个尚待澄清的因果关系问题。原文中涉及到的乙肝疫苗商品只有 15种 ,而全球上市的该疫苗品种也许是这个数字的数十倍。究竟哪种品种会引起不良反应 ?其流行病学的特点又如可 ?这也似乎是值得探讨的问题。我国人口众多 ,每年接受乙肝疫苗接种的人数何止千万 ,因此在我国进行乙肝疫苗不良反应的流行病学调研工作十分必要。现借原作者 (Myeboom)之所望 ,愿我国有关部门和广大同道们都来关注这一问题 This is a question of causality to be clarified. There are only 15 kinds of hepatitis B vaccine products covered in the original text, and the vaccine species listed on the world may be several times of this figure. Which species will cause adverse reactions? Its epidemiological characteristics, such as may also seem to be worth exploring. Because of the large population in our country, there are so many millions of people receiving hepatitis B vaccination each year. Therefore, it is very necessary to conduct an epidemiological investigation on the adverse reactions of hepatitis B vaccine in our country. By the hope of the original author (Myeboom), I hope that the relevant departments of our country and the general public will pay attention to this issue
