Antivenom (or antivenin or antivenene) is a biological product used in the treatment of venomous bites or stings. Antivenom is created by milking venom from the desired snake, spider or insect. The venom is then diluted and injected into a horse, sheep or goat. The subject animal will undergo an immune response to the venom, producing antibodies against the venom's active molecule which can then be harvested from the animal's blood and used to treat envenomation. Internationally, antivenoms must conform to the standards of pharmacopoeia and the World Health Organization (WHO).

The name "antivenin" comes from the French word venin, meaning venom, which in turn was derived from Latin venenum, meaning poison.

Historically antivenin was predominant around the world. The first published use of the term was in 1895. In 1981, the World Health Organization decided that the preferred terminology in the English language would be venom and antivenom rather than venin and antivenin or venen and antivenene.

Stan Lee (born December 28, 1922) is an American comic book writer, editor, actor, producer, publisher, television personality, and the former president and chairman of Marvel Comics.

In collaboration with several artists, most notably Jack Kirby and Steve Ditko, he co-created Spider-Man, the Hulk, the X-Men, the Fantastic Four, Iron Man, Thor, and many other fictional characters, introducing complex, naturalistic characters and a thoroughly shared universe into superhero comic books. In addition, he headed the first major successful challenge to the industry's censorship organization, the Comics Code Authority, and forced it to reform its policies. Lee subsequently led the expansion of Marvel Comics from a small division of a publishing house to a large multimedia corporation.

He was inducted into the comic book industry's Will Eisner Comic Book Hall of Fame in 1994 and the Jack Kirby Hall of Fame in 1995.

Stan Lee was born Stanley Martin Lieber in New York City on December 28, 1922, in the apartment of his Romanian-born Jewish immigrant parents, Celia (née Solomon) and Jack Lieber, at the corner of West 98th Street and West End Avenue in Manhattan. His father, trained as a dress cutter, worked only sporadically after the Great Depression, and the family moved further uptown to Fort Washington Avenue, in Washington Heights, Manhattan. When Lee was nearly 9, his only sibling, brother Larry Lieber, was born. He said in 2006 that as a child he was influenced by books and movies, particularly those with Errol Flynn playing heroic roles. By the time Lee was in his teens, the family was living in a one-bedroom apartment at 1720 University Avenue in The Bronx. Lee described it as "a third-floor apartment facing out back", with him and his brother sharing a bedroom and his parents using a foldout couch.
