New CDC data strengthen the evidence that the risk for Guillain-Barré syndrome (GBS) associated with the 2009 H1N1 vaccine is similar to the risk seen with seasonal flu vaccines, according to an MMWR report.

The CDC’s analysis of data from October 2009 through March 2010 found that the incidence of GBS was 1.92 per 100,000 person-years among vaccinated individuals and 1.21 per 100,000 person-years among the unvaccinated. If final data confirm this finding, the CDC says, then this would translate to 0.8 excess GBS cases for every 1 million vaccinations — a rate comparable to that found with seasonal flu vaccination.
