Study design showing a challenge model based on a three parallel tank system. Each of the vaccine groups was allocated 38 fish while the unvaccinated control group had 30 fish in each tank. At day 56 (8 weeks) post vaccination, fish were challenged with a highly virulent Norwegian IPNV strain NVI-015TA (AY379740) using a cohabitation model. In each tank, 13 fish injected with 1 × 107 TCID50/mL of the challenge virus were added to serve as virus shedders.
