(CBS) - A new study of the H1N1 vaccine finds it is associated with a small increased risk of a rare paralyzing condition called Guillain-Barre Syndrome. Federal researchers found 77 people came down with the rare illness within the first 3 months of getting vaccinated. That's more than twice as many cases as normal. In Guillain-Barre, the immune system attacks the body, affecting movement. It typically takes patients months to recover. 23 million people received the H1N1 vaccination in 2009. Researchers say the benefits far outweigh the risks.
