Thanks to samples taken from vaccination kits dating from the Civil War, they were able to discover how American soldiers were vaccinated during the second half of the 19th century.
And Edward Jenner invented vaccination
understanding the history, evolution and how viruses can function as vaccines is extremely important“even today,” explains geneticist Hendrik Poinar, co-author of a study published on July 20, 2020 in the journal and conducted by an international team. data-reactid = “25”> Smallpox was one of the most devastating viral diseases, killing three in ten people infected. The survivors were often disabled or disfigured. If it was finally eradicated in 1980 thanks to a massive campaign by the World Health Organization, it remains the only human infectious disease in this case even today. So “understanding the history, evolution and how viruses can function as vaccines is extremely important“even today,” explains geneticist Hendrik Poinar, co-author of a study published on July 20, 2020 in the journal and conducted by an international team.
Remarkable observer, he quickly unraveled the mystery: all contracted, in contact with the udder of the cow, the cowpox, that is to say the smallpox of the cow, benign disease which immunizes cheaply against the human smallpox, tells on his site.In 1796, Jenner inoculated a little cowpox (English name of the vaccine, editor’s note)in the arm of little James Phibbs, who never had smallpox. A pustule forms. Three weeks later, he inoculated her with human smallpox pus. Nothing follows. […]“data-reactid =” 26 “> The active fight against smallpox dates back to the year 1796 when the British Edward Jenner discovered that the vaccine, or cow pox, allows, if the virus is administered to humans, to fight actively against smallpox, more aggressive. Dr Edwar Jenner notices that some cowhorts do not seem to be affected by it. “Remarkable observer, he quickly unraveled the mystery: all contracted, in contact with the udder of the cow, the cowpox, that is to say the smallpox of the cow, benign disease which immunizes cheaply against the human smallpox, tells on his site.
