The Smallpox Vaccine

Smallpox and Biotechnology

• Perhaps one of the greatest examples of biotechnology at work

• Successful application has saved millions of lives

What is Smallpox?

• Disease that has existed for at least 3,000 years

• Highly contagious• Typically fatal

Symptoms

• Fever• Rashes on face, hands, and feet• Pus-filled pimples develop• Attacks brain, heart, and lungs

Edward Jenner

• Born May 1749• From Gloucestershire, England• Studied Anatomy and Surgery at hospital• Received many smallpox patients in 1788

The Theory

• Noted patients who worked with cattle were immune to smallpox

• These patients previously contracted cowpox• Suggested someone injected with cowpox

would be immune to smallpox

Testing the Theory

• Extracted liquid from sores of milkmaid with smallpox

• Injected cowpox into young boy• Boy recovers in 6 weeks, injects him with

smallpox• Experiment was successful; boy was immune

to smallpox

The Vaccine

• Time-tested and successful• World Health Organization declared smallpox

extinct in 1979• Excellent example of the application of

biotechnology
