Advice in the event of unintentional self-injection of fish vaccine
Preventive safety measures

It is important that people carrying out vaccination of farmed fish should follow the recommended preventive safety measures in order to minimise the risk of unintentional self-injection.

  • Effective training in vaccination technique, first aid and an introduction to precautions in the event of unintentional self-injection.
  • Correct fitting and use of a needle-guard on the syringe. The needle-guard should be fitted to the syringe to protect the vaccinator`s hand (especially fingers) from the needle point.
  • Use appropriate gloves to ensure a good grip on the fish.
  • Take regular breaks and ensure a comfortable working position and good lighting. Make sure the rate of vaccination does not affect quality and safety.
  • It is extremely important to ensure that the fish are properly anaesthetised. Many unintentional self-injections occur when fish wriggle.
  • Notify the local doctor prior to vaccination.
  • Products containing fish vaccine should not be administered by pregnant women.
  • Have first aid equipment and an adrenalin pen or a similar device ready for the treatment of anaphylactic reactions.
  • When using a vaccination machine it is very important to comply with the supplier's advice and warnings concerning the risk of accidental self injection. Do not touch the needle or the area close to its operating area when the machine is in use. In the case of accidental self injection by a machine the full dose will be injected. This increases the risk of serious side effects.

PHARMAQ's advice in the event of unintentional self-injection

To the vaccinator
If you have been accidentally injected with fish vaccine, seek the assistance of a doctor immediately, even if the injected amount is small. Take the package insert from the vaccine package with you to the doctor. If pain persists for more than 12 hours after medical examination, you must consult the doctor again.

Unintentional injection of fish vaccine can lead to severe pain and swelling, especially if the preparation is injected into a limb or a finger. In rare cases, the loss of an affected finger may be the result if treatment is not commenced immediately.

Repeated self-injection may result in an allergic reaction to the fish vaccine. If allergic patients inject themselves there is a risk of anaphylactic shock, which can be life-threatening without prompt and appropriate treatment.

To the doctor
The injection of even a small amount of a fish vaccine product can result in pronounced swelling which may, for example, result in ischaemic necrosis or even the loss of an affected finger.

The site of injection must IMMEDIATELY be examined by a surgically competent person, and if necessary, incision and irrigation of the affected area must be performed, especially when ligaments or soft finger tissue are involved.

Repeated self-injection may reinforce the reaction or result in anaphylactic shock.
