Smallpox

Question

Smallpox

BlackTom AI · Accepted Answer

Here’s a careful look at each option about Smallpox, examining what is factually correct or incorrect.
Option 1: 'the smallpox vaccine was derived from a less deadly virus infecting the American bison' This is not accurate. The smallpox vaccine was historically developed from cowpox virus (and related vaccinia strains in later formulations), not from a virus infecting American bison. The connection to bison is not part of the established vaccine origin.
Option 2: 'all are true' Given that some of the other statements are incorrect (notably 1 and 3, and the nuanced history around transmission direction in 3), declaring all of them true would be inconsistent with accepted scientific and historical records. Therefore this blanket option is unreliable.
Option 3: 'Was one of only a few diseases transmitted from Native Americans to Europeans' This misstates the historical transmission direction. Smallpox was introduced to the Americas primarily due to European contact, and it did not originate from Native American populations to Europeans. In epidemiological terms, the assertion about transmission from Native Americans to Europeans is inaccurate.
Option 4: 'is one of only a few human disease that have been eradicated from the global population' This is correct. Smallpox is widely recognized as one of the few diseases that have been eradicated globally through vaccination and global health campaigns. The other major candidate for eradication status is rinderpest in animals, but among human diseases, smallpox stands as a historic success story of eradication.
In summary, option 1 misstates the vaccine origin, option 3 reverses the direction of transmission, option 2 falsely claims all statements are true, and option 4 accurately reflects Smallpox’s eradication status.
