Vaxart to Present Key Data Related to Its Oral Norovirus and Seasonal Influenza Tablet Vaccines at the 9th Vaccine & ISV Congress in Seoul

SOUTH SAN FRANCISCO, Calif.

Vaxart, Inc., a privately held, clinical-stage biotechnology company developing oral recombinant vaccines that are administered by tablet rather than by injection, announced today that results from two studies will be presented at the 9th Vaccine & ISV Congress in Seoul, South Korea.

The first presentation will cover data demonstrating that Vaxart’s oral norovirus vaccine elicited a broader immune response when compared to an injectable VLP VP1 vaccine. The second presentation will highlight data from a recent Phase 1 clinical study demonstrating that the Vaxart’s H1N1 influenza tablet vaccine generated neutralizing antibodies in 92 percent of subjects after a single dose.

Vaxart vaccines are based on a versatile vector-based platform that is designed to be suitable for a wide range of infectious diseases. The company’s lead programs include tablet vaccine candidates for seasonal influenza, norovirus and Respiratory Syncytial Virus (RSV).
