Combination vaccine
The present invention relates to a vaccine, especially a combination vaccine providing at least a first and a second antigenic function, the combination vaccine comprising at least one RNA encoding at least one or more proteins or fragments, variants or derivatives of proteins awarding antigenic function, wherein the first antigenic function being a Fusion (F) protein or a fragment, variant or derivative of a Fusion (F) protein derived from the virus family Paramyxoviridae and the second antigenic function being an Hemagglutinin (HA) protein or a fragment, variant or derivative of an Hemagglutinin (HA) protein derived from the virus family Orthomyxoviridae. Furthermore, the present invention is directed to a kit or kit of parts comprising the components of said combination vaccine and to said combination vaccine for use in a method of prophylactic or therapeutic treatment of diseases, particularly in the prevention or treatment of infectious diseases like RSV and influenza.
1. A composition comprising an mRNA encoding an extracellular domain of a Fusion (F) protein from a virus of the family Paramyxoviridae, and an mRNA encoding an extracellular domain of a Hemagglutinin (HA) protein from a virus of the family Orthomyxoviridae.
2. The composition of claim 1 , comprising a first monocistronic mRNA that encodes the extracellular domain of the Fusion (F) protein and a second monocistronic mRNA that encodes the extracellular domain of the Hemagglutinin (HA) protein.
3. The composition of claim 1 , comprising a bicistronic or a multicistronic mRNA wherein at least one open reading frame encodes the extracellular domain of the Fusion (F) protein and wherein at least another open reading frame encodes the extracellular domain of the Hemagglutinin (HA) protein.
