Research Associate Molecular Biology

AstriVax is a privately held spin-off company from the KU Leuven, founded mid 2022 with a seed round of €30 million to bring our ambition to the next level. We are building a first in class Plug & Play vaccine platform with a patented DNA based technology that launches self-amplifying live attenuated viruses on which additional targets can be added. The versatile technology of AstriVax can be used to develop a wide range of vaccines to prevent and treat infectious diseases, up to potential applications in oncology. We aim to address major challenges in vaccinology by developing novel vaccines that are single dose (game changing in vaccine landscape), easy to produce and with reduced cold chain requirements. The live attenuated viruses being launched from our products induce a polyfunctional immune response which has the potential to address many unmet medical need targets.
