A fully licensed vaccine against human swine flu may not be ready until the end of the year, months after a second wave of flu is expected to hit Canada in the fall, World Health Organization officials said Monday. That would leave Canada and other nations to decide whether to invoke emergency 
measures and vaccinate people with only limited information about safety and dosing. A vaccine rushed into distribution against swine flu in 1976 in the U. S. caused high rates of Guillain-Barre syndrome, a rare and potentially paralyzing neurological disorder. Vaccines today "are much better purified than the way they were in 1976, so we really don't think that it is likely that we will have this side-effect again," Dr. Marie-Paule Kieny, director of WHO's initiative for vaccine research, said Monday. "But to be absolutely honest, of course, it's only when you have a large-scale distribution of vaccine that you know with certainty the safety profile of the vaccine."
