The history of smallpox extends into pre-history; the disease likely emerged in human populations about 10,000 BC. The earliest credible evidence of smallpox is found in the Egyptian mummies of people who died some 3000 years ago. Smallpox has had a major impact on world history, not least because indigenous populations of regions where smallpox was non-native, such as the Americas and Australia, were rapidly decimated and weakened by smallpox (along with other introduced diseases) during periods of initial foreign contact, which helped pave the way for conquest and colonization. During the 18th century the disease killed an estimated 400,000 Europeans each year, including five reigning monarchs, and was responsible for a third of all blindness. Between 20 and 60% of all those infected—and over 80% of infected children—died from the disease
Smallpox was responsible for an estimated 300–500 million deaths during the 20th century.
As recently as 1967, the World Health Organization (WHO) estimated that 15 million people contracted the disease and that two million died in that year.After successful vaccination campaigns throughout the 19th and 20th centuries, the WHO certified the global eradication of smallpox in December 1979. Smallpox is one of two infectious diseases to have been eradicated, the other being rinderpest, which was declared eradicated in 2011

Yet you vaccinate your dog............:
Tetanus
The ntroduction of TT vaccines in the 1930s and 1940s, which led to universal childhood immunization and the addition of decennial TT boosters for adults (2,3). A major contributor to the decline in morbidity was the near elimination of neonatal tetanus, a result attributable to improved childbirth practices and to increased levels of maternal immunity resulting from universal childhood vaccination
Reported tetanus cases have declined >95%, and deaths from tetanus have declined >99% in the United States since 1947, when the disease became reportable nationally. CDC analyzed cases reported to the National Notifiable Diseases Surveillance System (NNDSS) during 2001--2008. This report summarizes the results of that analysis, which found that 233 tetanus cases were reported during 2001--2008; among the 197 cases with known outcomes, the case-fatality rate was 13.2%.
TT vaccination status was reported for 92 (39.5%) of the 233 patients. A total of 37 patients (40.7%) received no TT doses, 26 (28.3%) received 1 dose, five (5.4%) received 3 doses, and 24 (26.1%) received ≥4 doses (Table 2). Among the 36 patients aged ≥50 years, five (13.9%) reported completing the primary 3-dose TT series, compared with 24 (42.9%) of the 56 aged <50 years. Seven (24.1%) of 29 patients with ≥3 doses of TT had received their last dose within 10 years, 18 (62.1%) from 10 to 54 years previously, and four (13.8%) reported an unknown interval since their last dose.
