Saint-Herblain (France), March 8, 2020 – Valneva SE (“Valneva” or “the Company”), today announced that the Food and Drug Administration (FDA) has approved the extension of the shelf life of its Japanese encephalitis vaccine IXIARO® from 24 months to 36 months.

Separately, the US Department of Defense (“DoD”) has issued a Request for Proposal (“RFP”) for Japanese Encephalitis Vaccine. This RFP covers a period of three years comprising one year plus two years of options. Valneva will respond to this RFP expeditiously and, if successful, expects to enter into a new supply contract during the first half of 2020.

Franck Grimaud, Valneva’s Chief Business Officer, commented, “We are pleased to receive this valuable shelf life extension for IXIARO® in the US. We also look forward to continuing to work closely with the DoD and to meeting their requirements. The U.S. military has been using IXIARO® for the past ten years and we look forward to continuing to help protect US troops, their families, military retirees, and government service personnel from this potentially deadly disease.”

About Japanese Encephalitis

Japanese encephalitis is a deadly infectious disease found mainly in Asia. About 70,000 cases of JE are estimated to occur in Asia each year, although the actual number of cases is likely much higher due to underreporting in rural areas. JE is fatal in approximately 30 percent of those who show symptoms, and leaves half of survivors with permanent brain damage. The disease is endemic in Southeast Asia, India and China, a region with a population of more than three billion. In 2005, JE killed more than 1,200 children in only one month during an epidemic outbreak in Uttar Pradesh, India, and Nepal.
