Why it is on the platform

Cold chain is roughly a fifth of the delivered cost of a vaccine dose in low-infrastructure markets. Removing it is a cost argument before it is a humanitarian one — which is what makes it fundable.

Traction

  • Three model antigens stable for 26 weeks at 30 °C.
  • Joint feasibility programme with a mid-size European vaccine producer.
  • Priority patent filed on the excipient family.

Use of funds

  • Extend the panel to mRNA and viral-vector formats.
  • GMP-compatible process definition.
  • Two paid feasibility programmes with manufacturers.
