Efficacy of Three Vaccine Regimens Against Infectious Hematopoietic Necrosis Virus Transmission Potential in Rainbow Trout

Collectively, our results suggest that existing IHNV vaccines that increase host survival provide minimal virus transmission protection in rainbow trout, which is likely to limit their long-term efficacy in the field. This work contributes to a growing body of evidence that enhancement of the transmission protection of IHNV and other vaccines will likely bolster disease reduction in the field.
