Vaxdyn was founded in 2011 as a spin-off established by researchers of the Institute of Biomedicine of Seville, a center of the Andalusian Public Health System and the University of Seville linked to the University Hospital Virgen del Rocío of Seville. Our mission is to prevent and alleviate the global health crisis caused by the pathogenic bacteria resistant to antibiotics. We work with an international network of collaborators on development of multi-valent vaccines for preventing antibiotics-resistant infections in all regions of the world.
