VLP technology is central to OptiMalVax (malaria), Prevent-nCoV (SARS-CoV-2 spike protein VLP), and connects to their recombinant protein work in INDIGO.
EXPRES2ION BIOTECHNOLOGIES APS
Danish biotech SME providing recombinant protein and virus-like particle technology for vaccine development against malaria, influenza, and coronaviruses.
Their core work
ExpreS2ion Biotechnologies is a Danish biotech SME specializing in recombinant protein production and virus-like particle (VLP) technology for vaccine development. They provide their proprietary insect cell expression platform to produce complex antigens — particularly for malaria, influenza, and coronavirus vaccines. In H2020 consortia, they serve as the protein/antigen manufacturing partner, enabling other teams to test vaccine candidates that require correctly folded, high-yield recombinant proteins.
What they specialise in
OptiMalVax and MultiViVax both target Plasmodium parasites across multiple lifecycle stages using recombinant antigens and SpyCatcher conjugation.
INDIGO project focuses on recombinant HA production, HA deletion mutants, and needle-free intradermal delivery — their largest single grant at EUR 610K.
Prevent-nCoV demonstrated their ability to pivot quickly to SARS-CoV-2 spike protein VLP production during the COVID-19 pandemic.
How they've shifted over time
Their early H2020 work (2017) was rooted in tropical disease — specifically malaria vaccines targeting multiple Plasmodium lifecycle stages, using SpyCatcher multi-antigen conjugation and antigen discovery. From 2020 onward, they shifted toward respiratory virus vaccines (influenza and COVID-19), incorporating delivery innovations like microneedle patches and needle-free intradermal systems. This trajectory shows a company moving from niche tropical disease antigens toward broader infectious disease vaccine platforms with global market potential.
ExpreS2ion is broadening from tropical disease antigens toward pandemic-relevant respiratory vaccines with advanced delivery formats — expect continued work on VLP platforms for emerging infectious diseases.
How they like to work
ExpreS2ion operates exclusively as a specialist participant — they have never coordinated an H2020 project, instead contributing their protein expression technology to consortia led by others. With 41 unique partners across 12 countries in just 4 projects, they join large, multinational research consortia where their role is clearly defined as the antigen/protein production specialist. This makes them a reliable, low-friction partner: they bring a specific capability without competing for consortium leadership.
Despite only 4 projects, they have built a wide network of 41 partners in 12 countries — indicating participation in large consortia typical of global health vaccine research. Their collaborators likely span European universities, tropical disease institutes, and clinical trial organizations.
What sets them apart
ExpreS2ion's differentiator is their proprietary insect cell (Drosophila S2) expression system, which produces complex recombinant proteins that are difficult to manufacture in standard systems like E. coli or CHO cells. This makes them a go-to partner when a consortium needs correctly folded, glycosylated antigens for vaccine candidates. For consortium builders, they offer a plug-in manufacturing capability for vaccine antigens — a specific, hard-to-replace technical contribution that de-risks the protein production step.
Highlights from their portfolio
- INDIGOTheir largest grant (EUR 610K) and most recent active project, combining recombinant influenza antigens with needle-free delivery — signals their strategic direction.
- OptiMalVaxMulti-antigen malaria vaccine using SpyCatcher conjugation across all parasite lifecycle stages — technically ambitious and their second-largest funding (EUR 445K).
- Prevent-nCoVRapid COVID-19 response project demonstrating their ability to pivot VLP technology to a new pathogen under pandemic urgency.
