| Abstract: | Thirty-six persons -- veterinarians, technicians and students at a veterinary clinic -- were unwittingly exposed to a rabid dog over a period of 21/2 days. One veterinarian received a penetrating bite, two other individuals were grabbed by the dog but the skin was not penetrated, and many were exposed to saliva or urine or both. In addition, the owner of the dog and his wife and three children, while not bitten, were exposed to saliva. The diagnosis was made post mortem when specimens of the dog''s brain were examined by indirect fluorescent antibody testing. All but one of the students had been vaccinated against rabies with hamster kidney vaccine, but eight members of the veterinary college''s staff had not been so vaccinated. Treatment started with duck embryo vaccine; if necessary, rabies (human) immune globulin was also given. When one student reacted severely to the first dose of duck embryo vaccine permission was sought to bring a human diploid vaccine into Canada. In five patients the human diploid vaccine was substituted for the duck embryo vaccine because of severe reactions to the latter. Twenty-five staff members and the family of five received both vaccines. Reactions to the human diploid vaccine were minor and transient. Recommendations include the early licensing of the human diploid vaccine in Canada. |
