Onset of immunity:
500 degree days after vaccination for the bacterial antigens and 608 degree days after vaccination for IPNV.
Duration of immunity:
A. salmonicida and M. viscosa: 18 months.
L. anguillarum O1, L. anguillarum O2a and V. salmonicida: 16 months.
Infectious pancreatic necrosis virus: 4 months.
Contraindications
None.
Special warnings for each target species
The vaccine should not be used in diseased or unhealthy fish, fish receiving medical treatment, or fish during smoltification.
Do not vaccinate below 2.5 °C or above 17 °C.
Vaccination at high water temperatures (≥ 17 °C) may increase local reactions.
Incorrect vaccination, stress and poor hygiene may lead to increased side effects.
Operator Warnings
Personal protective equipment consisting of guarded needles or needle protectors should be used when administering the product.
In case of accidental self-injection, seek medical advice immediately and show the package leaflet or label to the physician.
To the user:
This veterinary medicinal product contains mineral oil. Accidental injection/self-injection may result in severe pain and swelling, particularly if injected into a joint or finger, and in rare cases could result in the loss of the affected finger if prompt medical attention is not given.
If you are accidentally injected with this product, seek prompt medical advice even if only a very small amount is injected and take the package leaflet with you.
If pain persists for more than 12 hours after medical examination, seek medical advice again.
To the physician:
This veterinary medicinal product contains mineral oil. Even if small amounts have been injected, accidental injection with this product can cause intense swelling, which may, for example, result in ischaemic necrosis and even the loss of a digit. Expert, PROMPT, surgical attention is required and may necessitate early incision and irrigation of the injected area, especially where there is involvement of finger pulp or tendon.
Adverse Reactions
Oil adjuvant increases the risk of side effects after vaccination in the form of adhesions and pigmentation in the abdominal cavity.
Moderate adhesions and pigmentation in the abdominal cavity are very commonly observed.
Vaccine residues occur very commonly.
Adhesions with a Speilberg score of 1 to 3 are commonly seen with most of the scores ≤ 2. More extensive changes (Speilberg score 4) uncommonly occur.
A reduction in appetite after vaccination is very commonly observed. The loss of appetite is most pronounced during the first week after vaccination and feed intake is restored within 10 - 12 days. Appetite loss after vaccination does not affect weight at harvest.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated reports)
Use during pregnancy or lactation
Do not use in broodstock. The possible effects of vaccination on spawning have not been investigated.
Interactions
No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product. A decision to use this vaccine before or after any other veterinary medicinal product therefore needs to be made on a case-by-case basis.
Amounts to be administered and administration route
Intraperitoneal use.
Shake the bottle well before use.
Dosage: a single dose of 0.1 ml.
Administration: intraperitoneally along the central line, approximately 1 pelvic fin length in front of the pelvic fin base in Atlantic salmon.
Vaccination is recommended for fish above 30 grams.
Food should be withheld at least 2 days prior to vaccination.
The fish should be anaesthetised before vaccination.
The length and the diameter of the applied needle should be adapted to the actual fish size. Ensure that the recommended dose is deposited into the abdominal cavity before the needle is withdrawn.
Overdose
Following the administration of a 2x overdose, no reactions other than those described in section ‘Adverse Reactions’ were observed.
Withdrawal periods
Zero degree days.
