Mean S2 cDNA copy number and infectivity at viraemic peak. A S2 cDNA mean copy number at viraemic peak by tested serotype and vaccinated status. B Infectivity at viraemic peak, expressed as mean Log TCID50/mL of blood titre by tested serotype and vaccinated status. Dotted line represents the classical threshold of 103155 TCID50/mL required to allow BTV transmission to vector Culicoides. *For NV_BTV4, one animal had no detectable viraemia at all was excluded from calculation. Error bars represent standard deviation.
