No increase in Gullain Barre incidence with H1N1 2009 vaccination-says CDC

The preliminary results from the last H1N1 2009 vaccination season are in. So far no excess cases have been reported with the vaccine when compared to previous vaccination years. More people developed Guillain Barre without vaccination than with the vaccine (total numbers). The rate of cases per 100,000 population were slightly greater in those with vaccination than those without vaccination (0.8 per 100,000 persons greater). These results are consistent with the expected safety profile as seen in previous years.

No statistically significant association between GBS and 2009 H1N1 vaccination has been seen
