Study summary

It is the aim of the present study to compare the immunogenicity induced by a laser-assisted epidermally administered seasonal influenza vaccine to an intradermally administered seasonal influenza vaccine.

Read the detailed description

The skin is an attractive tissue for vaccination due to the impact of the cutaneous micro-environment on the adaptive and non-adaptive immune responses. Conventionally many vaccines are administered subcutaneously. Immune-competent cells however are not resident in the subcutaneous fat tissue, but instead are located in the epidermis and the dermis of the skin. Depending on the targeted skin layer and administration method, different immunological outcomes are thus anticipated following vaccination.

In the present study, the immunogenicity (in terms of activation of B-cell mediated and T-cell mediated immune responses) of laser-assisted epidermally administered seasonal influenza vaccine will be compared to needle-based intradermal administration of the same seasonal influenza vaccine.

Study arms

  • Experimental
    Laser assisted epidermal application

    Laser pretreatment: 4 adjacent areas of 2 cm² each (14mm x 14 mm) will be pretreated with an Erbium Yttrium Aluminium Garnet laser (22,7 J/cm², 2 pulses, Density: 5%) generating micropores with a depth of approximately 91 µm. 0,1 ml of Intanza (15 µg, seasonal trivalent influenza vaccine) will be topically administered on the laser-treated area.

    Biological: seasonal influenza vaccine · Device: fractional Er:Yag laser

  • Active comparator
    Intradermal application

    0,1 ml of Intanza (15 µg, seasonal trivalent influenza vaccine) will be intradermally injected in the deltoid area.

    Biological: seasonal influenza vaccine

Interventions

  • Biologicalseasonal influenza vaccine

    influenza vaccine containing 15 µg haemagglutinin of three seasonal influenza virus strains recommended by WHO

    Also known as: INTANZA

  • Devicefractional Er:Yag laser

    Fraction laser device to apply micorpores of defined depth and density into skin.

    Also known as: Pantec P.L.E.A.S.E.
