Vaccination remains the most effective method of preventing influenza its consequences, however, vaccine effectiveness decreases increasing age immunosenescence. In adults, immunogenicity studies suggest an MF59 adjuvanted (ATIV, Fluad ® ) may help. Methods We evaluated comparative ATIV, unadjuvanted trivalent (TIV) reducing laboratory confirmed elderly. Elderly three health authorities during winter 2011–12 were included community based case control study design. Cases tested positive controls negative for influenza. Subjects known immunosuppression excluded. Logistic regression was used to calculate odds ratio vaccination (vs. no vaccination) cases controls. ATIV TIV described. Results A total 282 eligible participants enrolled (84 cases). Almost half (136) long term care facility 85 years or (132) decreased age. variety multivariate analyses, significantly protective at around 60% ( p = 0.02), only residence authority also significant.
