About Medicago

Medicago is a clinical-stage biotechnology company, developing effective and competitive vaccines based on proprietary Virus-Like Particles (VLP) and manufacturing technologies. Medicago is developing VLP vaccines to protect against pandemic and seasonal influenza, using a transient expression system which produces recombinant vaccine antigens in non-transgenic plants. This technology has potential to offer advantages of speed and cost over competitive technologies. It could deliver a vaccine for testing in about a month after the identification and reception of the genetic sequence. This production time frame has the potential to allow vaccination of the population before the first wave of a pandemic strikes and to supply large volumes of vaccine antigens to the world market.
