Duration of immunity: immunity has not been studied beyond 28 days (336
degree days).

booster vaccination is required to extend the duration of immunity for a further 28
days then the intraperitoneal route should be used.
When administering by immersion, dilute the contents immediately after opening
the container, and use diluted vaccine immediately.
The development of protective immunity is dependent on the water temperature.
Shake the bottle before use.
Primary vaccination by immersion (Fish of at least 5 g)
Dilute the contents of the bottle (1 litre) in 9 litres of hatchery water, clean and
suitably oxygenated.
Place the fish into batches and immerse for 30 seconds in the diluted vaccine.
A litre of vaccine (making 10 litres of diluted vaccine) allows the vaccination of a
maximum of 100 kg of fish.

The vaccine must be administered using a multi-dose injection applicator
incorporating a mechanism to prevent flush-back. This applies equally to hand-
