The use of small pox in

Wright, [57] an African American and Harvard Medical School graduateintroduced intradermal vaccination for smallpox for the soldiers while serving in the Army during World War I. Perhaps if I live to return I may, however, have courage to war with them. It contains live vaccinia virus, cloned from the same strain used in an earlier vaccineDryvax.

As the campaign neared its goal, Fenner and his team played an important role in verifying eradication. On average, 3 out of every 10 people who got it died. Vaccination within three to seven days after exposure to smallpox may prevent the disease in rare cases, but usually limits its symptoms, and is thought to reduce mortality.

Activated T-cells replicate, and their offspring become memory T-cells. The drug must be administered intravenouslyand may cause serious kidney toxicity. In the first week, the bump becomes a large blister called a "Jennerian vesicle" which fills with pus, and begins to drain. On October 22, he developed a fever.

Smallpox virus is injected into the bloodstream. Potentially life-threatening reactions occurred in 14 to people out of every 1 million people vaccinated for the first time. Inthe four countries that either served as a WHO collaborating center or were actively working with variola virus were the United States, England, Russia, and South Africa.

It was transmitted from one person to another primarily through prolonged face-to-face contact with an infected person, usually within a distance of 1. The patients would then develop a mild case of the disease and from then on were immune to it. His report, published for the first time inwas sceptical and called for further vaccinations.

However, the Faculty favoured variolation and took no action. Efficacy and adverse reaction incidence are similar to Dryvax. The use of smallpox virus in a bioterrorist attack could have a devastating impact, since this virus can spread easily by airborne infection and its infectivity is strong. No regular account is kept of births and deaths, but when smallpox, measles or malignant fevers make their appearance in the house, the mortality is very great.

Smallpox is a contagious disease caused by the variola virus.; Smallpox was the first disease to be eliminated from the world through public health efforts and vaccination. Smallpox still poses a threat because people could use existing laboratory strains as biological weapons.

History of Smallpox
