H1N1 vaccine not a high risk for Guillain-Barre syndrome

There is no more notable risk of a form of paralysis for people who received H1N1 pandemic influenza vaccine compared to those who received a seasonal flu shot.

The information, according to CIDRAP News, comes from preliminary findings released by the US Centers for Disease Control and Prevention . The full results are expected to be ready to be released in the fall.

The paralytic condition, called Guillain-Barre syndrome, according to CIDRAP News, can be a rare side effect of the vaccination and has been linked to the 1976 swine flu vaccine. The CDC's Emerging Infections Program announced that the condition appeared on average in .8 cases per 1 million vaccinations, as compared to about 10 cases per 1 million during the 1976 influenza scare.

People hospitalized with GBS after Sept. 30, 2009, were contacted for the study to determine their vaccination history.

The information about the GBS patients - 326 of those who participated met the case criteria, according to CIDRAP News - was compared with the CDC's data for vaccinated and unvaccinated populations collected in the agency's Behavioral Risk Factor Surveillance System and a national phone survey about the H1N1 flu.

The findings, released in the recent  Morbidity and Mortality Weekly Report, appear to show that there is not a significant statistical connection between GBS and the H1N1 vaccine.
