Several oral immunizations are required to maintain a long-term protection against SRS. Salmonids from different aquaculture industries were first immunized with an injectable mono or polyvalent vaccine against SRS. The arrows at 1700 and 2900 degree-days indicate the time-point where first and second oral vaccines were administrated, respectively. Serum samples were obtained at different degree-days to determine specific IgM anti-P. salmonis. Samples were statistically analyzed by one-way ANOVA – Dunnet post-test. (SRS 150 fish/point, ISAv 70 fish/per point) *p < 0.05; **p < 0.01; ***p < 0.001.
