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 a Dales EM category of P. It is assigned the Condit map location U12. 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.
