摘要: Influenza and its complications disproportionately affect the elderly, leading to high morbidity mortality in this ever-increasing population. Despite widespread vaccination efforts, current influenza vaccines are less effective elderly; hence newer vaccine strategies needed improve their efficacy age group. We have previously shown that co-presentation of cytokines on surface inactivated virus particles affords better protection from lethal homotypic viral challenge young adult mice than conventional non-adjuvanted whole vaccine. Here, we determined these formulations Balb/c “aged” 17 months (“aged mice”) along with addition a membrane-bound interleukin-12 (IL-12) formulation. Our investigations found single low-dose intramuscular co-presenting IL-12 was sufficient provide enhanced subsequent as c...
