Vaccination: Lessons from history #2
Text
Smallpox likely emerged in human populations about 10,000 BC
The disease killed an estimated 400,000 Europeans annually during the closing years of the 18th century.
80% of infected children died from the disease and it was responsible for a third of all blindness.
Smallpox was responsible for 300-500 million deaths during the 20th century.
Following vaccination campaigns throughout the 19th and 20th centuries the WHO certified the eradication of smallpox in 1979.
Smallpox might have gone away; but it was only everyone worldwide vaccinating that eradicated this deadly disease.
Remember--Vaccinations Save Lives.
