Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this open label, single centre, pilot randomized controlled clinical trial the investigators aim to compare the immunogenicity and safety of a new influenza vaccination strategy consisting in the topical administration of imiquimod at the injection site before vaccination vs. a standard intramuscular vaccine injection in SOT recipients and HIV-infected individuals. The investigators planned to enroll 70 outpatients patients (50% solid-organ transplant recipients and 50% HIV-infected patients) regularly followed at the Transplantation center and the Infectious disease outpatients' clinics of the Lausanne University Hospital. Study participants will be randomized in a 1:1:1 ratio to receive the standard intramuscular vaccine (control group) or a topical application of an imiquimod containing cream followed by intramuscular (imiquimod-IM) or intradermal (imiquimod-ID) vaccine injection. After vaccination participants will be followed for a period of 180 days. Blood samples will be drawn at baseline and at day 21 and 180 for assessment of immunogenicity. Safety outcomes will be assessed immediately after vaccine administration, and at day 7 (phone call), 21 and 180.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intramuscular vaccine

The control intervention consists in the administration of the standard intramuscular influenza vaccine (Mutagrip®), containing 15 μg of each of the three viral strains without imiquimod.

Group Type ACTIVE_COMPARATOR

Mutagrip

Intervention Type BIOLOGICAL

Imiquimod and intradermal vaccine

In the imiquimod and intradermal vaccine arm, intervention consists in the topical application of a single bag of Aldara™ creme 5%, containing 12.5 mg of imiquimod, on a 16 cm2 square delimitated area on the non-dominant arm at the time of influenza vaccination. An intradermal influenza vaccine preparations containing 15 μg of each of the three viral strains (Intanza®) will be administrated in the centre of the marked area after the imiquimod cream is fully absorbed.

Imiquimod and intramuscular vaccine

In the imiquimod and intramuscular vaccine arm, intervention consists in the topical application of a single bag of Aldara™ creme 5%, containing 12.5 mg of imiquimod, on a 16 cm2 square delimitated area on the non-dominant arm at the time of influenza vaccination. An intramuscular influenza vaccine preparations containing 15 μg of each of the three viral strains (Mutagrip®) will be administrated in the centre of the marked area after the imiquimod cream is fully absorbed.
