Thefluoropeptide vaccine technology then delivers these antigens into the body and promotes robust T-cell immunity without requiring potentially toxic adjuvants which are normally used with vaccines to boost the responses achieved. The company was founded in late 2003 and is located at the London BioScience Innovation Centre, based in London. In June 2007 the company raised its first major venture capital funding from a syndicate of investors including the Novartis Venture Fund, HealthCap, Truffle Capital & the London Technology Fund.
