We focus on the discovery, development, manufacturing and marketing of vaccines and antibodies to protect people from infectious diseases.

Novel technologies are used to make sure that the processes are safe, reliable, scalable and cost-effective, so that the vaccines can be produced in large quantities at low costs.
