Summary
Fish vaccine self-injections pose low health risks to vaccinators, with allergic reactions being rare. Improved safety measures and training have reduced incidence and severity of adverse events.
Area of Science:
- Veterinary Medicine
- Occupational Health
Background:
- Adverse health events in vaccinators from accidental fish vaccine self-injection necessitate risk factor identification.
- Understanding these risks is crucial for improving safety protocols in aquaculture vaccination practices.
Observation:
- Professional vaccinators reported frequent self-injections, primarily on hands and fingers.
- Two cases of anaphylactic reactions requiring hospitalization were documented.
- Clinical presentations of self-injection injuries were categorized by severity.
Findings:
- The overall risk of serious health effects from fish vaccine self-injection is low.
- Allergic hypersensitivity reactions were observed in a small number of vaccinators.
- No infectious reactions were reported, suggesting non-steroid anti-inflammatory drugs as appropriate therapy.
Implications:
- Implementation of safety devices (e.g., safety bows) and enhanced personnel training have decreased self-injection incidents.
- Equipping vaccinators with adrenaline and improving local physician knowledge on treatment further mitigate health risks.
- These combined strategies significantly enhance safety for vaccinators in the aquaculture industry.
