The present disclosure is directed to peptide antigens derived from a previously undefined epitope on influenza A virus hemagglutinin and methods for use thereof.

The present invention relates to TLR2 agonist compounds and their compositions, and the use of such compounds and compositions in the prevention and/or treatment of respiratory infections, or diseases or conditions associated with viral or bacterial infections.

Disclosed is a pharmaceutical unit dosage composition including a plurality of enteric coated micro pellets. Each enteric coated micro pellet includes a core bead, an optional first sealing layer, an API layer including a Compound (I) having the following structure or a pharmaceutically acceptable salt thereof, an optional second sealing layer, and an enteric coating layer. Also disclosed is a method for the treatment and prophylaxis of RSV diseases including providing a Compound (I) and administering to a patient in need thereof a therapeutically effective amount of the Compound (I) so that t½ of the Compound (I) is about 6 to 13 hours.

##STR00001##

The invention concerns a trans-splicing RNA (tsRNA) molecule comprising one or multiple unstructured binding domains; a cell or vector comprising said tsRNA; and a method for killing cells or treating a disease using said tsRNA.

The present invention provides novel methods and compositions for use in preventing infection with at least one type of influenza virus, including the use of peptides or compositions comprising a peptide comprising, consisting or consisting essentially of an amino acid sequence selected from the group of sequences as shown in SEQ ID Nos: 1 to 53, or functional derivatives or homologues thereof.

The present invention provides a modified influenza viruses comprising haemagglutinin and a headless haemagglutinin. The haemagglutinin is provided by a source exogenous to the virus and the headless haemagglutinin is encoded by the viral genome. The present disclosure also provides modified influenza viruses comprising a headless haemagglutinin. The present disclosure also provides vaccine compositions comprising the modified influenza viruses. The vaccine compositions of the present disclosure can elicit broad neutralizing antibodies and provide cross-protection across various influenza strains. Methods, compositions and cells for propagating the modified influenza viral strains related to vaccines is also provided.
