疫苗的出现是人类在20世纪取得的最伟大的成就之一,许多严重威胁人类生命健康的疾病逐步得到拉制,甚至被消灭。如天花曾肆虐一时夺去了无数人的生命,自从出现天花疫苗后,发病率逐渐下降,1976年世界卫生组织宣布天花在世界上已经绝迹。还有,脊髓灰质炎(小儿麻痹症)在没有出现疫苗前,也是一种危害极大的传染病,致残率很高;疫苗出现后,发病率逐年下降,我国已经有几年没有发现新发病人。其他诸如麻疹疫苗、百—白—破疫苗、乙肝疫苗等,接种后,相应疾病也逐步得到了有效控制,发病率逐年下降。可是这“救世主”还会给人类带来灾难吗?今年6月份发生在黑龙江省密山市的“一起疫苗事件”提醒我们,对疫苗还要多做宣传和推介,让普通老百姓都了解它。
