Vaccine Adjuvant Research
Most modern vaccines consist of small parts from the virus or bacterium that cause disease. Although these are carefully chosen to trigger protection from the disease, they are insufficient as an effective vaccine per se. Thus, they cannot alert the immune system sufficiently to activate it - this problem is solved by adding adjuvants.
At SSI we develop liposome-based adjuvant systems. These liposomes are designed to effectively activate the immune system. The result is a very effective vaccine directed precisely against the parts of the microorganism that provide the best protection. We aim to rationally design adjuvants to give immune profiles matching the challenges posed by different microorganisms.
Our core adjuvant system, named CAF, is recognized by vaccine researchers worldwide:
CAF01
The first adjuvant in the CAF series is called CAF01. Clinical trials in humans have shown that it is both safe and highly effective, both for inducing antibody responses and at activating vaccine-specific helper T cells that play an important role in the immune response against e.g. tuberculosis: A novel liposomal adjuvant system, CAF01, promotes long-lived Mycobacterium tuberculosis-specific T-cell responses in humanand Chlamydia: Safety and immunogenicity of the chlamydia vaccine candidate CTH522 adjuvanted with CAF01 liposomes or aluminium hydroxide: a first-in-human, randomised, double-blind, placebo-controlled, phase 1 trial
CAF09b
The adjuvant CAF09b activates killer T cells of the immune system, which play an important role in the fight against e.g. cancer and viruses. CAF09b has been tested in humans in a vaccine against prostate cancer: First in man study: Bcl-Xl_42-CAF®09b vaccines in patients with locally advanced prostate cancer and in a neoantigen-based vaccine against metastatic melanoma: Personalized therapy with peptide-based neoantigen vaccine (EVX-01) including a novel adjuvant, CAF®09b, in patients with metastatic melanoma
CAF10b
CAF10b is designed to effectively stimulate a component of the T cell immune response named Th17 cells. CAF10b is currently undergoing evaluation in humans in a vaccine against Mycobacterium tuberculosis: First-in-Human Trial of the Novel Tuberculosis Vaccine Candidate, H107e/CAF®10b (nTB-01)
Research projects
NeoPepVac
Title: Personalized cancer immunotherapy using adjuvanted Neo-epitope Peptide based Vaccines (NeoPepVac)
Objective: The overall aim of the project is to generate personalized immune therapy vaccines that are likely to be highly efficacious in a large fraction of cancer patients and strengthen the effect of check-point inhibitors. The four specific objectives are: to develop personalized cancer vaccines based on peptides in combination with the CAF09b adjuvant designed to provide optimal immunotherapy through CTL induction to complete a phase l trial with neoepitope based immunotherapy in cancer patients and provide PoC for the overall strategy, safety and clinical feasibility improve prediction algorithms, through identification of neoepitopes using syngenic mouse models and in-depth analyses of immune reactivity in vaccinated patients to develop vaccine delivery strategies to broaden the neoepitope repertoire and increase the response and efficacy of the vaccine.
Participants: NeoPepVac is a Danish consortium comprising 4 partners, Statens Serum Institut, Evaxion Biotech, Technical University of Denmark and Herlev Hospital
Funded by: Innovation Fund Denmark
TransVac2
Title: European Vaccine Research and Development Infrastructure
Objective: The objective of the Transvac2 consortium is to further advance the establishment of a fully operational and sustainable European vaccine R&D infrastructure. TransVac2 will support innovation for both prophylactic and terapeutic vaccine development based on a disease-overarching and one-health approach, thereby optimizing the knowledge and expertise gained during the development of both human and animal vaccines.

RNA vaccines collaboration programme
Title: RNA vaccines collaboration programme
Objective: The objective of this project is to develop new improved mRNA vaccine constructs or mRNA vaccine delivery systems.
Participants: The RNA vaccines collaboration programme is a Danish consortium comprising Statens Serum Institut, University of Copenhagen and University of Aarhus.
Funded by: Novo Nordisk Foundation
FLUniversal
Title: Intranasal, rapid-acting vaccine for all seasonal and pandemic influenza viruses
Objective: The FLUniversal consortium aims to develop DeltaFLU as a universal influenza vaccine that protects against all influenza virus strains. To accelerate the clinical development of influenza vaccine candidates in general, FLUniversal will also develop a controlled human infection clinical challenge model and assess correlates of protection against influenza virus.
Participants: FLUniversal is a European consortium comprising Vivaldi Biosciences, Leiden University Medical Center (LUMC), Statens Serum Institut (SSI), Vismederi, The Centre for Human Drug Research (CHDR), Meditox and MHRA.
Funded by: European Union H2020
AVAR-T
Title: ADVANCING VACCINE ADJUVANT RESEARCH FOR TUBERCULOSIS
Objective: The purpose of the AVAR-T consortium is to develop novel vaccine adjuvants that can accelerate tuberculosis vaccine development. Different antigen/adjuvant combinations will be benchmarked in an unbiased fashion, to propose antigen/adjuvant formulations to move forward.
Participants: AVAR-T is an international consortium comprising partners from Australia (University of Sydney), United States (Oregon Health & Science University) and Denmark (Statens Serum Institut).
