The present invention provides a viral vector or bacterial vector, said vector comprising a nucleic acid sequence encoding a Crimean-Congo Haemorrhagic Fever Virus (CCHFV) glycoprotein or antigenic fragment thereof; wherein said vector is capable of inducing an immune response in a subject. The present invention also provides compositions and uses of the vector in methods of medical treatment.

The invention relates to vaccine compositions including CEV serogroup immunogens, attenuated and inactivated viruses of the CEV serogroup and chimeric Bunyaviridae. Also disclosed are methods of treating or preventing CEV serogroup infection in a mammalian host, methods of producing a subunit vaccine composition or an immunogenic composition, isolated polynucleotides comprising a nucleotide sequence encoding a CEV serogroup immunogen, methods for detecting La Crosse virus (LACV) infection in a biological sample and infectious chimeric Bunyaviridae.

A nucleic acid molecule including a translation control element having a translation initiation activity and a coding region operably linked to the translation control element and encoding an immunogen of an influenza virus or a severe fever with thrombocytopenia syndrome virus (SFTSV) or fragments thereof is disclosed. The nucleic acid molecule or an expression system where the nucleic acid molecule is inserted can be used in a pharmaceutical composition for treating or preventing influenza or SFTS, for example, that an mRNA vaccine or a gene therapy platform.
