Abstract

Classic Kaposi's sarcoma (cKS) is a human herpesvirus-8 (HHV-8)-associated lympho-angioproliferative tumor typically occurring in the elderly. It is associated with HHV-8-driven perturbed balance of peripheral B-cell subsets, which may have an impact on immune responses to antigenic stimulation. We took advantage of the common practice of cKS patients to undergo seasonal influenza vaccination because of advanced age and analyzed the immunogenicity and safety of licensed trivalent influenza vaccine in 46 cKS patients and 44 matched controls. Licensure criteria for immunogenicity were fulfilled in both groups. Four weeks after vaccination, hemagglutination-inhibition antibody titers against each viral strain contained in the vaccine increased in patients and controls (all P0.001). Protection against at least one strain was achieved by 96% of cKS and 91% of control subjects. Protection against all strains persisted after 12 weeks, demonstrating a long-lasting response to vaccination. The vaccine was equally well tolerated by patients and controls, as assessed by evaluating solicited local and systemic reactions to the vaccine, and appearance or increase of antinuclear autoantibodies. HHV-8 virological rebound was observed in four cKS patients, but was not accompanied by progression of KS lesions. We conclude that seasonal influenza vaccine given to cKS patients is immunogenic and safe.
