AgFunder, Fall Line Capital.


Mazen is an animal health company developing novel biological vaccines and therapeutics to replace existing injectable vaccines. They have developed a vaccine platform that uses maize as a biofactory for the production of recombinant vaccines. This enables the delivery of oral vaccines in an edible form providing distinct advantages over injectables, topicals, and water-based orals.

Why we invested

  • Protein producers are facing a number of challenges with the current vaccination process (low efficacy rates, labor shortages, worker welfare, animal welfare, biosecurity) that support the quick adoption of shelf-stable, needleless oral vaccines. 
  • Mazen has an extraordinary management team of seasoned industry experts.
  • While Mazen is an animal health company first, they have the potential to become a platform for the production of all kinds of high-value recombinant proteins.
