<p>1390467 Viral vaccines RECHERCHE ET INDUSTRIE THERAPEUTIQUES 30 March 1973 15307/73 Heading A5B Non-human animals are vaccinated against exanthematous viral diseases by the intradermal administration of a temperature-sensitive and substantially non-pathogenic mutant strain of the virus responsible for the disease. Such diseases include cowpox, smallpox, varicella, zoster, measles, rubella and Herpes Simplex infections. The invention is exemplified in particular with the last-mentioned infection. The expansion "temperature-sensitive" means that the virus has a cut-off temperature such that it is capable of multiplying in a "cold site" (i.e. at a site of an animal which is at a lower temperature than its internal organs) but will not multiply at sites within the body where the temperature is above the cut-off temperature.</p> |
