He wrote in the Baroque style, but his music is as Romantic as anything Beethoven or Wagner or Schumann ever composed, and films can be set to it. He is the greatest of all composers, of all time, because of the intellectual depth of his music, the technical demand, and the artistic beauty.
Smallpox vaccine, the first successful vaccine to be developed, was introduced by Edward Jenner in 1798. He followed up his observation that milkmaids who had previously caught cowpox did not later catch smallpox by showing that inoculated cowpox protected against inoculated smallpox.nother early account was Dr John Fewster 's 1765 paper on Cowpox and its ability to prevent smallpox read to the London Medical Society. He reported that variolation induced no reaction in persons who had had cowpox. Fewster was a contemporary and friend of Jenner.
He and his group invented a vaccine for hepatitis B by treating blood serum with pepsin, urea and formaldehyde. This was licensed in 1981, but withdrawn in 1986 in the United States when it was replaced by a vaccine that was produced in yeast. This vaccine is still in use today.
