Article Synopsis
- Arctic foxes were immunized with a lyophilized SAG2 oral rabies vaccine, and the study assessed its effectiveness through serologic response and survival after rabies exposure.
- Vaccine virus was not detected in the saliva shortly after ingestion, but all vaccinated foxes showed a strong immune response within two weeks and survived for 17 weeks post-challenge.
- The findings indicate that the SAG2 oral rabies vaccine is likely effective in arctic and subarctic areas, where extreme temperatures do not compromise its ability to stimulate immune responses.
Fifteen collared lemmings (Dicrostonyx groenlandicus) were exposed to a lyophilized oral rabies vaccine designed to immunize wild carnivore populations. No animals contracted rabies from the vaccine as determined by the absence of clinical signs after 37 days and lack of rabies virus in brain tissue determined by the fluorescent antibody (FA) test. These results suggest that collared lemmings would not contract rabies if they ingested this lyophilized vaccine in the wild during bait vaccination programs for arctic foxes (Alopex lagopus).
