Disclosed are peptides comprising a monomeric Fc fragment of an immunoglobulin recognized by a neonatal receptor (FcRn); a modified pre-fusion respiratory syncytia virus (RSV) F protein; and a trimerization domain. Disclosed are nucleic acid sequences capable of encoding peptides comprising a monomeric Fc fragment of an immunoglobulin recognized by a neonatal receptor (FcRn); a modified pre-fusion respiratory syncytia virus (RSV) F protein; and a trimerization domain. Also disclosed are methods for eliciting a protective immune response against RSV comprising administering to a subject an effective amount of a composition comprising a monomeric Fc fragment of an immunoglobulin recognized by FcRn; a modified pre-fusion RSV F protein; and a trimerization domain, wherein the administering is to a mucosal epithelium.

The invention relates to an immunization regimen whereby an infant is protected against respiratory syncytial virus (RSV) through administration of a first anti-RSV immune response inducing composition to his or her mother during pregnancy, followed by administration of a second anti-RSV immune response inducing composition to the infant after birth.

The present invention pertains to a strategy of selectively targeting oncolytic virotherapy, using either naturally occurring or genetically modified viruses by packaging them in mesenchymal stem cells (MSCs). The present invention concerns MSCs, compositions comprising the MSCs, and methods of using the MSCs for treatment of cancer and for lysing or inducing apoptosis of cancer cells in vitro or in vivo.

The invention provides methods for using virus-like particle (VLP) vaccines containing a stabilized pre-fusion respiratory syncytial virus (RSV) F protein to stimulate RSV neutralizing antibodies in pre-immune subjects. In one embodiment, the invention provides a method for immunizing a mammalian subject in need of immunizing against Respiratory Syncytial virus (RSV) infection, comprising, a) providing i) a pre-immune mammalian subject containing RSV neutralizing antibodies, ii) a first composition comprising recombinant chimeric Newcastle disease virus-like particles (ND VLPs), that contain a chimeric protein comprising, in N operable combination, 1) stabilized pre-fusion RSV F protein ectodomain, 2) transmembrane (TM) domain of NDV F protein, and 3) cytoplasmic (CT) domain of NDV F protein, and b) administering an immunologically effective amount of the first composition to the pre-immune subject to produce an immunized subject that comprises an increase in the level of the RSV neutralizing antibodies compared to the level of RSV neutralizing antibodies in the pre-immune subject. In one embodiment, the level of the RSV neutralizing antibodies in the pre-immune subject does not prevent RSV infection of the pre-immune subject.

The present invention relates to the epicutaneous vaccination against RSV vaccination with a skin patch device loaded with a particle exposing an RSV-F protein, a variant or a fragment thereof.

The present invention relates to novel nucleic acid molecules encoding a pre-fusion RSV F protein or immunologically active part thereof, wherein the pre-fusion RSV F protein comprises the amino acid sequence of SEQ ID NO: 1 or 2. The invention further relates to the use of the nucleic acid molecules, or vectors comprising said nucleic acid molecules, as a vaccine against respiratory syncytial virus (RSV).

The disclosure relates to respiratory virus ribonucleic acid (RNA) vaccines as well as methods of using the vaccines and compositions comprising the vaccines.

Recombinant, live, attenuated viruses of the Pneumoviridae family are disclosed that include a baculovirus GP64 envelope glycoprotein or variant or fragment thereof and a respiratory syncytial virus (RSV) F protein variant or fragment thereof. Also disclosed are polynucleotides encoding the virus as well as pharmaceutical compositions and vaccines containing the virus. In addition, methods of producing and using each of the above compositions are also disclosed.

The present invention relates to novel nucleic acid molecules encoding a pre-fusion RSV F protein or immunologically active part thereof, wherein the pre-fusion RSV F protein comprises the amino acid sequence of SEQ ID NO: 1 or 2. The invention further relates to the use of the nucleic acid molecules, or vectors comprising said nucleic acid molecules, as a vaccine against respiratory syncytial virus (RSV).

Methods of inducing a protective immune response against respiratory syncytial virus (RSV) and against influenza virus, without inducing a severe adverse event in human subjects are described. The methods include administering to the subjects an effective amount of an adenoviral vector encoding a recombinant RSV F polypeptide that is stabilized in a pre-fusion conformation, along with an effective amount of an influenza vaccine.
