Gardasil Linked to Nerve Disorder

Cervical Cancer Vaccine May Raise Risk of Guillain-Barre Syndrome

Guillain-Barre Syndrome and Vaccination: Study Details

For the study, researchers examined data from the Vaccine Adverse Event Reporting System (VAERS), which is managed by the CDC and the FDA.

There were 53 cases of Guillain-Barre reported after HPV vaccination in the United States from 2006 to 2008. In nearly three-fourths of cases, the disorder developed within six weeks after vaccination. More than one-third of cases occurred in the first two weeks.

The fact that so many cases occurred in the first few weeks after vaccination strongly suggests that “some cases are caused by the vaccine,” Souayah says.

Merck spokeswoman Pamela Eisele points to the FDA and CDC statement on the safety of Gardasil: “The FDA and CDC have reviewed the reports of GBS that have been submitted to VAERS. To date, there is no evidence that Gardasil has increased the rate of GBS above that expected in the population.”

Gorson says much more study is needed before any conclusions regarding Gardasil and GBS can be made. Plus, the chance of developing Guillain-Barre syndrome, regardless of whether you’re vaccinated, is extremely low, he says.

“I would discourage women to look for the problem in the first six weeks after vaccination as it will just cause undue anxiety. Guillain-Barre syndrome is not subtle, with weakness, paralysis, balance problems, and numbness and tingling of the limbs developing in a rapidly progressing fashion. It won’t be missed,” Gorson tells WebMD.
