Metapneumovirus (MPV) F proteins stabilized in a prefusion conformation, nucleic acid molecules and vectors encoding these proteins, and methods of their use and production are disclosed. In several embodiments, the MPV F proteins and/or nucleic acid molecules can be used to generate an immune response to MPV in a subject. In additional embodiments, the therapeutically effective amount of the MPV F ectodomain trimers and/or nucleic acid molecules can be administered to a subject in a method of treating or preventing MPV infection.

Methods of safely inducing a protective immune response against respiratory syncytial virus (RSV) and methods of preventing infection and/or replication of RSV in human subjects are described. The methods include administering to the subjects (a) an effective amount of an adenoviral vector encoding a recombinant RSV F protein that is stabilized in a pre-fusion conformation, and (b) an effective amount of an RSV F protein that is stabilized in a pre-fusion conformation.
