Progressive vaccinia associated with combined variable immunodeficiency.

Progressive vaccinia developed in a previously healthy woman following smallpox vaccination and was successfully treated with vaccinia immune human globulin and methisazone. Immunologic evaluation over the next 4 1/2 years revealed evidence for combined variable immunodeficiency with increased numbers of circulating OKT 8 positive (suppressor-cytotoxic T) cells and the virtual absence of OKT 4 positive (helper-inducer T) cells.
