Co-expressing BTV-4 VP2 and BTV-8 VP2 in rMVA in IFNAR(-/-) mice abolishes neutralizing antibody induction, despite generating non-neutralizing antibodies to both VP2 proteins.
- Why it matters: Multiserotype bluetongue control is limited by vaccine safety, lack of broad protection, and inability to support DIVA differentiation.
- What they did: The study used recombinant Modified Vaccinia Ankara vectors expressing VP2 from BTV serotypes 4 and 8 either singly or together, then measured immunogenicity and protection in IFNAR(-/-) mice and sheep.
- The result: Monovalent rMVA prime-boost in IFNAR(-/-) mice induced strong neutralizing responses and complete protection against lethal BTV-4 or BTV-8 challenge, and in sheep it produced nAbs to both serotypes with full protection against BTV-4 and protection against BTV-8 with mild RNAemia.
