| abstractText | Profound alterations in humoral and cellular immune responses are a hallmark of aging, and understanding the immunobiology of aging is key to the success of preventive vaccination strategies. With aging, while recall or memory responses to influenza viral antigens for the most part remained unaltered, primary immune responses are severely impaired. The impaired primary responses are partly due to a lack of costimulation, as providing costimulation at the time of induction of primary immune responses against influenza virus vaccine partially reversed aged-related immune dysfunction and conferred enhanced protection. Inclusion of immunomodulators that up-regulate the expression of costimulatory molecules must be considered to improve the efficacy of vaccination in the elderly, particularly to novel immunogens.
