Researchers from the U.S. Centers for Disease Control and Prevention and the Kaiser Permanente Vaccine Study Center studied cases of Guillain-Barre syndrome (GBS) in California over a 13-year period and found no link between the paralyzing syndrome and vaccines. During the study period, only 25 of the 415 patients confirmed with GBS had received a vaccine six weeks prior to the disease’s onset. “Although we had limited power to fully assess the risk of GBS following vaccination due to the rarity of the outcome, the low numbers of GBS cases that were temporally associated with vaccination, coupled with our results, provide reassurance that the risk of GBS following any vaccine, including influenza vaccines, is extremely low,” say the researchers, led by Dr. Roger Baxter, co-director of the Kaiser Permanente Vaccine Study Center. The study is published in Clinical Infectious Diseases.
