Influenza is an important pathogen in transplant recipients. The current widespread outbreak of highly pathogenic H5N1 avian influenza (HPAI) in livestock, and the occurrence of several human cases of infection suggest that the next influenza pandemic may be soon approaching. Transplant patients will likely be uniquely predisposed to serious infection with high morbidity and mortality. There are a number of important reasons that evaluation of prevention strategies are critical in this highly vulnerable population. Currently, there is no data on the immunogenicity of H5Nx vaccines in this highly vulnerable population. The investigators plan to study the safety and immunogenicity of a two-dose regimen of the pandemic influenza H5N1 vaccine in organ transplant patients.
