A.Pandemrix causes autoimmune reaction to happen
B.people genetically at risk tend to develop narcolepsy
C.autoimmune reaction results in narcolepsy

细节推理题。根据第四段中的Researchers suspect an autoimmune reaction is to blame because many people who develop narcolepsy...have a specific variant in a gene in the HLA family(研究人员怀疑应该归咎于自身免疫反应，因为很多患有嗜睡症的人……在HLA家族的基因中有一个特定的变异体)可推测有遗传风险的人往往会患上嗜睡症，故选B。
