1. A nanostructure, comprising:
(a) a plurality of first assemblies, each first assembly comprising a plurality of identical first polypeptides;
(b) a plurality of second assemblies, each second assembly comprising a plurality of identical second polypeptides, wherein the second polypeptide differs from the first polypeptide;
wherein the plurality of first assemblies non-covalently interact with the plurality of second assemblies to form a nanostructure; and
wherein the nanostructure displays multiple copies of one or more paramyxovirus and/or pneumovirus F proteins, or antigenic fragments thereof, on an exterior of the nanostructure.
