Dr. Sejvar added that the CDC “is doing several active assessments of the risk of GBS and other neurologic events following the H1N1 vaccine.” These include the CDC Emerging Infections Program, which includes population-based active surveillance for GBS risk following H1N1 vaccination, and the Vaccine Safety Data Link, a “large, population-based, linked database in which we’re assessing potential risk for GBS and other events following H1N1 and seasonal influenza” vaccination, he said.

“Rest assured that we are doing additional, active population-based studies to more proactively assess this risk,” Dr. Sejvar concluded.
