Smallpox vaccination provides full immunity for 3 to 5 years and decreasing immunity thereafter. If a person is vaccinated again later, immunity lasts even longer. Historically, the vaccine has been effective in preventing smallpox infection in 95% of those vaccinated. In addition, the vaccine was proven to prevent or substantially lessen infection when given within a few days of exposure. It is important to note, however, that at the time when the smallpox vaccine was used to eradicate the disease, testing was not as advanced or precise as it is today, so there may still be things to learn about the vaccine and its effectiveness and length of protection.

(1749–1823) . For centuries smallpox was a scourge. The dread disease killed or left weakness and hideous scars. When late in the 18th century Edward Jenner, a young physician, startled the medical profession by claiming that people who had had cowpox would not get smallpox, his theory was scorned. After many years, however, doctors began using Jenner’s method, based upon his theory, of preventing smallpox. He called the method vaccination. By 1979 the disease was declared eradicated (see vaccines).

Smallpox is a contagious, disfiguring and often deadly disease that has affected humans for thousands of years. Naturally occurring smallpox was eradicated worldwide by 1980 — the result of an unprecedented global immunization campaign. Stockpiles of smallpox virus have been kept for research purposes. This has led to concerns that smallpox could someday be used as a biological warfare agent. There's no treatment or cure for smallpox. A vaccine can prevent smallpox, but the risk of the vaccine's side effects is too high to currently justify routine vaccination for people at low risk of exposure to the smallpox virus.
