Thanks nickcarraway. There was no such vaccine available in 1787, btw, the attempt was a crapshoot with not too good results. This article is just some stupid COVID stooge agitprop.
from the wikiwacky: [snip] In 1796, the British doctor Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus. Cowpox served as a natural vaccine until the modern smallpox vaccine emerged in the 20th century. From 1958 to 1977, the World Health Organization conducted a global vaccination campaign that eradicated smallpox, making it the only human disease to be eradicated. Although routine smallpox vaccination is no longer performed on the general public, the vaccine is still being produced to guard against bioterrorism, biological warfare, and for monkeypox. [/snip]
Some might argue nt much has changed.
