A 20-month-old girl was diagnosed with Guillain - Barré syndrome (GBS) based on progressive muscle weakness, areflexia, and albuminocytologic dissociation of the cerebrospinal fluid. Despite timely and systematic treatment, she eventually became paralyzed. There is a temporal correlation between the girl's GBS and the DTaP vaccination, but the exact causal relationship between the two is still debatable. Furthermore, we summarized clinical features of other 45 published GBS cases after DTP vaccines (or vaccine substances containing tetanus) through a systematic review. The mean onset age, sex distribution, onset time after vaccination, detection of antiganglioside antibodies, and other basic clinical features of GBS after DTP vaccination (or vaccine substances containing tetanus) were analyzed. The temporal pattern of GBS after vaccination was similar to that of GBS after infection. Herein, we report this rare case of presumptive pediatric GBS after DTaP vaccination and review similar cases to draw the attention of medical personnel to similar events after vaccination. An association between DTP vaccines and GBS has been proposed, and the causal relationship between these two incidents are worthy further exploration. Moreover, surveillance and vigilance for GBS after vaccination are highly recommended.
