Aquavac Relera vet.
Active substance
ATC code
Species
Rainbow trout (Oncorhynchus mykiss).
Indications
Active immunisation against Enteric Redmouth disease (ERM) to reduce mortality caused by Hagerman type 1 and EX5 biotype strains of Yersinia ruckeri.
Immersion route:
Onset of immunity: 336 degree days (28 days at 12 °C) for Hagerman type 1 and for EX5 biotype.
Duration of immunity:
6 months (205 days at 12 °C) for the Hagerman type 1. 4 months (133 days at 12 °C) for the EX5 biotype.
Please note that the level of protection against the EX5 biotype wanes during the indicated period.
Intraperitoneal route (only for booster vaccination):
Duration of immunity: immunity has not been studied beyond 28 days (336 degree days).
Dose to be administered and administration route
Primary vaccination should be by the immersion route only. In the event that a 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.
Booster vaccination by intraperitoneal injection (Fish of at least 12 g) The vaccine must be administered using a multi-dose injection applicator incorporating a mechanism to prevent flush-back. This applies equally to handheld and automatic systems.
The product is administered by intraperitoneal injection in the ventral area, just anterior to the pelvic fins. The dose is 0.1 ml per fish. The fish should be anaesthetised prior to vaccination.

Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system.
