The Swiss Mymetix Corporation (OTC:OTCQB:MYMX) is the third company exploring the nasal route. They share intellectual property with US giant Catalent (NYSE:CTLT) about packing antigenic material in virus-like particles for local application (so-called virosomes). Their nasal COVID-vaccine developed with Baylor College in Texas gave promising preclinical data in animal experiments. It might be of interest that they have the support of the Bill Gates foundation and of billionaire Ernesto Bertarelli.
