The Guillain–Barré Syndrome and the 1992–1993 and 1993–1994 Influenza Vaccines

Abstract

There was no increase in the risk of vaccine-associated Guillain-Barré syndrome from 1992-1993 to 1993-1994. For the two seasons combined, the adjusted relative risk of 1.7 suggests slightly more than one additional case of Guillain-Barré syndrome per million persons vaccinated against influenza.
