Most of our fish vaccines contain formalin-inactivated bacterial and/or viral antigens, as well as oil adjuvants. The injection dose varies from 0.025 to 0.1ml depending on the vaccine. In some cases, more than one vaccine may be injected simultaneously in order to deliver multiple antigens. The injection is made into the abdominal cavity of the fish. This is done either manually or by machine.
Adjuvants, such as aluminum salts and mineral oil, are sometimes added to vaccines in order to enhance the immune response. Liquid paraffin is the most commonly used mineral oil in veterinary vaccines.
Most mineral oils are considered tissue irritants. This means that even small amounts can cause significant harm and inflammation when injected into human tissue. It is therefore important that anyone who believes that they may have accidentally injected themselves is taken to hospital immediately.
Mineral oils in the fish vaccines contain powerful tissue toxins. We advise that injuries should be examined by a medical professional as soon as possible, preferably within a few hours. Surgical interventions – such as incision and irrigation – might be required.
Antibiotics and painkillers are insufficient as exclusive treatments. Antibiotics may be used in cases of bacterial infection. Anti-inflammatory pain killers can be useful in reducing pain and inflammation. An anti-tetanus injection is normally not required.
If a needle that has been in contact with fish vaccine has penetrated your skin, you must seek medical assistance immediately – even if you believe that little or no vaccine has been injected.Advice in the event of self-injection
