Our lead program, VLA15, is a Phase 2 vaccine candidate targeting Borrelia, the bacterium that causes Lyme disease, under development in collaboration with Pfizer, and it is the only active vaccine candidate against Lyme disease currently undergoing clinical trials.  Our clinical portfolio includes VLA1553, targeting the chikungunya virus, which has spread to more than 100 countries and infected more than 3 million people in the Americas since first arriving there in 2013. To our knowledge, VLA1553 is the only chikungunya vaccine candidate in Phase 3 clinical trials.

We are advancing VLA2001, a highly purified, inactivated and adjuvanted vaccine candidate against the SARS-CoV-2 virus that causes COVID-19 in order to address the urgent, global need for billions of doses of vaccines. VLA2001 is currently the only inactivated vaccine candidate for COVID-19 in clinical trials in Europe. We believe that, if approved, our vaccine, as an inactivated virus vaccine, could offer benefits in terms of safety, cost, ease of manufacture and distribution compared to currently approved vaccines and could be adapted to offer protection against mutations of the virus.
