Be forewarned, please, that this will not be very pleasant reading, especially if readers eat farm-raised fish and, in particular, salmon, a highly-farm-raised fish. “Wild-caught” need not apply.
During my years of research, I’ve come across all sorts of information, studies, and papers relating to animal vaccines, but this one sort of “takes the cake,” in my opinion. Farmed fish are vaccinated because, according to the Norwegian School of Veterinary Science (NSVS),
Modern fish farming is highly industrialized and relies heavily upon effective vaccines to minimize losses caused by infectious diseases. 
Want to know how to vaccinate a fish?
Please see slide 4 of the 28-slide presentation, “Side-effects of vaccination: an example of the conflict between guidelines and real life.”
It looks like a PowerPoint presentation made by Trygve T. Poppe and Gunvor Knudsen of the NSVS.
