| Abstract: | Genetic engineering techniques have been used to construct a vaccinia virus recombinant which contains and expresses togavirus (Sindbis) genetic information. Intradermal inoculation of this recombinant strain into calves caused a transient pock-type lesion at the site of inoculation and elicited the production of substantial levels of anti-Sindbis virus neutralising antibodies. These results suggest that recombinant vaccinia virus vaccines may have potential for use in veterinary medicine. |
