Intravacc - innovating vaccines

Even the most promising vaccines don’t always make it out of the laboratory into large-scale production.

We at Intravacc are fully aware of the challenges on the long road of vaccine development. We substantially reduce the risks and costs involved with developing vaccines.

How? By bridging the gap between your concept and late stage clinical studies.

GMP facilities

At Intravacc we have two GMP facilities on the campus, Intravacc and BuildingX. We offer pilot GMP production of both viral, bacterial and cancer vaccines. A variety of production technologies are available in both single-use or stainless steel bioreactors.

At Intravacc, the GMP cleanrooms (class c) and quality control span 230 sqm. In BuildingX four labs are available for BSL3 activities (165 sqm). Two of these labs can be used for GMP activities.

Through our partnership network we can produce up to 100 million doses of vaccine.

Intravacc’s proprietary scalable
platform technologies

Intravacc has 4 platforms for vaccine development:

  • Outer Membrane Vesicles (OMV) – Bacterial and Viral
  • Cell-based viral – Vero and HEK 293; vector
  • Conjugation – Infectious diseases; in combination with OMV
  • Adjuvant – LPS and OMV

Conjugate vaccines

Conjugate vaccines have been extremely successful in preventing disease and death caused by bacterial
infections. Moreover, conjugate vaccines have a superb safety record with very few serious adverse events
following immunization. Intravacc has a 20-year track record in designing, developing and characterizing
conjugate vaccines.

A conjugate vaccine is created by covalently attaching a bacterial polysaccharide, which by itself is not able to induce immunological memory, to a protein carrier antigen, thereby eliciting a stronger immunological response to the antigen.

Outer Membrane Vesicles (OMV) platform

A novel approach for vaccines is the use of Outer Membrane Vesicles (OMVs). Gram-negative bacteria naturally release OMVs. OMVs are spherical particles (±20-200 nm) that harbour many bacterial antigens which play a role in establishing the infection and survival of the bacterium within the host.

The strongest asset of OMV vaccines is the native conformation of protective antigens. Intravacc has extensive expertise developing OMV vaccines and uses this as a platform technology for various vaccines.

Vero cell platform technology

The Vero cell line is the most widely used and most reliable cell line in viral vaccine production in terms of quality, yield and safety. At Intravacc, we have been developing viral vaccines using the Vero cell line since 1987.

Intravacc’s cGMP-grade, regulatory approved Vero cell line is currently being used for routine large-scale commercial vaccine manufacturing by clients all over the world.

Virus rescue: tailor-made virus strains

Every viral vaccine project starts with the selection of a virus strain. But finding suitable starting material can be a challenge.
Intravacc can solve these problems for you by designing your viral vaccine candidate and rescuing it, using our reverse genetics system. The result will be a tailor-made infectious progeny virus that you can passage and amplify as required.
