This mutant strain was derived by Samuel Dales from the IHD-W strain of Vaccinia (ATCC VR-1441) which in turn was derived from the IHD-J strain.

Non-permissive incubation temperature is 39.5C. This mutant was assigned to Dales EM category P indicating that it has immature normal particles and mature particles with cores that are predominantly lucent at the center. It is also assigned the Condit map location U9. This subtype is distinguishable from the parent IHD-J strain by its ability to elicit polykaryocytosis in all mammalian and avian cells tested and by its inability to induce an active hemagglutinin at the plasma membrane. This mutant was selected after mutagenesis with nitrosoguanidine and replication in the presence of bromodeoxyuridine.
