Maybe? It's formulated really badly, you don't know if they mean the virus or the traps...
"Subsequent in vivo (within a living organism) testing on mice showed the DNA-origami traps were capable of targeting individual virions inside the body, disarming them without disrupting bodily functions, and finally destroying them with natural immunological mechanisms."
free floating DNA is a pathogenic state of affairs and will be phagocytosed, the aptamer/virion complex will be shredded and the molecular debris is incorporated into antigen presenting complex initiating development of immunity
