Novavax Produces MERS-CoV Vaccine Candidate

Gaithersburg, Maryland, UNITED STATES

ROCKVILLE, Md., June 6, 2013 (GLOBE NEWSWIRE) -- Novavax, Inc. (Nasdaq:NVAX) announced today that it had successfully produced a vaccine candidate designed to provide protection against the recently emerging Middle East Respiratory Syndrome Coronavirus (MERS-CoV). The vaccine candidate, which was made using Novavax' recombinant nanoparticle vaccine technology, is based on the major surface spike (S) protein. The Company believes that its MERS-CoV vaccine candidate may provide a path forward for a vaccine for this emerging threat.

MERS-CoV is a novel coronavirus first identified in September 2012 by an Egyptian virologist, who isolated the previously unknown coronavirus from the lungs of a 60-year-old patient with pneumonia and renal failure. To date, the World Health Organization (WHO) has reported a total of 53 laboratory-confirmed cases of infection with MERS-CoV, including 30 deaths. The newly emergent virus is a part of the coronavirus family that includes the severe acute respiratory syndrome coronavirus (SARS-CoV), first recognized as a global threat in March 2003 and by July 2003, had resulted in 8,098 SARS cases in 26 countries, with 774 deaths.

Novavax had previously produced a recombinant nanoparticle vaccine candidate for the SARS-CoV virus which was similarly based on its major surface S protein. Novavax' SARS-CoV vaccine candidate study demonstrated immunogenicity and complete protection of animals in a live viral challenge; the study was published in the journal Vaccine (online 14 July, 2011).

MERS-CoV was first reported in Saudi Arabia and has spread to Europe, including England, France, Germany and most recently Italy. Health officials do not know how the newly discovered MERS-CoV spreads, making the development of an effective vaccine an important public health priority.
