The story
Vaccinogen originated in work done by the company's founder, Dr Michael Hanna, in the late 1970s and early 1980s when he was Director of the National Cancer Institute's Frederick Cancer Research Center in Frederick, Maryland. Hanna founded a company to develop what became OncoVAX and this was acquired by a company from Seattle called Intracel, but that company filed for bankruptcy in 2001. Vaccinogen was formed in 2007 to pick up the intellectual property and other assets from Intracel. Dr Ben Carson was chairman of the company from August 2014 until the announcement of his US presidential bid in May 2015. Carson had previously served on Vaccinogen's Medical Advisory Board.
