[Frequency and clinical consequences of self-injection among salmon vaccinators]. / Hyppighet og kliniske følger av selvstikk hos laksevaksinatører.

As general practitioners in one of Norways largest fish farming regions, we carried out a prospective study of 12 vaccinators of salmon in order to determine the frequency of self-injection, and the subsequent clinical reactions. The study was carried out in close cooperation with the local responsible veterinarian. We recorded 2,430,615 vaccinations of vaccine in salmon and smolt during the spring of 1992, with 12 accidental self-injections among the vaccinators. Clinical reactions were reported in four cases. There were only moderate local reactions. In our opinion, most of the reactions were of an inflammatory nature and were not caused by microbial infection. We question the first-choice, routine treatment with antibiotics that has been practised by physicians.
