There is no treatment for progressive vaccinia, and its death rate can be as high as 36 percent.

There is no cure for progressive vaccinia, Dr. Neff said.

It is effective for treatment of eczema vaccinatum and certain cases of progressive vaccinia.

He developed progressive vaccinia and AIDS, and died.

Progressive vaccinia (Vaccinia gangrenosum, Vaccinia necrosum)

He said his greatest concern was the threat of progressive vaccinia in immunocompromised people, either those vaccinated when they should not be or contacts of vaccinated people.

A little more than 14 people per million will suffer life-threatening reactions, including encephalitis and progressive vaccinia, a disease that resembles smallpox with fluid-filled sores covering the body.

There were no deaths from encephalitis, eczema vaccinatum, progressive vaccinia or the other side effects predicted last year based on studies from smallpox vaccination drives in the 1960's.

Persons with HIV infection or AIDS are at increased risk of progressive vaccinia (vaccinia necrosum) following vaccinia vaccination.

People whose immune systems have been weakened by AIDS or certain cancers, or by radiation, chemotherapy, steroids or drugs used to prevent transplant rejection, may be prone to an illness known as progressive vaccinia.

Progressive vaccinia (also known as "Vaccinia gangrenosum," and "Vaccinia necrosum") is a rare cutaneous condition caused by the vaccinia virus, characterized by painless, but progressive, necrosis and ulceration.

People with immune disorders are at risk, either through being vaccinated or through contact, for a potentially fatal condition called progressive vaccinia, in which the sore at the vaccination site keeps growing and spreading, and systemic illness develops.

They are prone to an illness called progressive vaccinia, in which the sore that normally forms at the vaccination site expands abnormally, growing larger and larger, causing tissue death and a systemic infection that may be uncontrollable.

Based on past experience, it is estimated that 1 or 2 people in 1 million (0.000198%) who receive the vaccine may die as a result, most often the result of postvaccinial encephalitis or severe necrosis in the area of vaccination (called progressive vaccinia).

Patients whose immunity has been lowered by illness or by medicines used to prevent transplant rejection have an increased risk for a potentially fatal reaction known as progressive vaccinia, in which the sore that normally forms at the vaccination site expands abnormally, damaging tissues all over the body.
