For the next eighty to one hundred years, smallpox and other diseases devastated native populations in the region. Puget Sound area populations, once estimated as high as 37,000 people, were reduced to only 9,000 survivors by the time settlers arrived en masse in the mid-19th century. Smallpox epidemics in 1780–82 and 1837–38 brought devastation and drastic depopulation among the Plains Indians. By 1832, the federal government established a smallpox vaccination program for Native Americans ("The Indian Vaccination Act of 1832"). It was
