Abstract | BACKGROUND: We hypothesized that low dose intradermal vaccination of the trivalent influenza vaccine (TIV) delivered by the MicronJet600 (NanoPass Technologies, Israel) would be non-inferior to the full dose intramuscular and mid dose Intanza((R)) vaccination in the elderly and the chronically ill adults. METHODS: We performed a prospective randomized trial on elderly and chronically ill adults. Subjects were randomly assigned into 4 groups. Groups ID3 and ID9 received reduced dose ID TIV (3 mug and 9 mug of hemagglutinin (HA) per strain respectively) delivered by MicronJet600 (NanoPass Technologies, Israel). Group INT9 received reduced dose ID TIV (9 mug) delivered by Becton Dickinson's Soluvia device (Intanza((R))9, Sanofi-Pasteur, France). Control group IM15 received a full dose IM TIV (15 mug). We measured antibody titers by hemagglutination inhibition (HAI) and microneutralization (MN) assays at baseline and day 21. RESULTS: Baseline characteristics for all groups were similar (group and sample sizes: ID3=63; ID9=68; INT9=65; and IM15=66). At day 21 post vaccination, the GMT ratio and the seroconversion rates difference for all three strains of the ID vaccine groups were non-inferior to the IM vaccine group. The seroconversion rate, seroprotection rate, and the GMT of the H1N1 strains by HAI and MN assays were significantly higher in the ID groups compared with the full dose IM vaccine group. The seroconversion rates of the H3N2 strain by HAI assay were also significantly higher in the ID groups when compared with the full dose IM group. Direct comparison among the three ID groups showed no significant differences. No serious adverse events related to vaccination were reported. CONCLUSION: Dose-sparing ID TIV can overcome reduced immunogenicity of the H1N1 strain, and according to some measures, for the H3N2 strain. At risk subjects indicated for the TIV should be considered for intradermal immunization to compensate for reduced immunogenicity. |
