About Vaxart

Vaxart is a clinical-stage biotechnology company focused on developing
oral recombinant protein vaccines based on its proprietary oral vaccine
platform. Vaxart’s vaccines are designed to generate broad and durable
immune responses that protect against a wide range of infectious
diseases and may also be useful for the treatment of chronic viral
infections and cancer. Vaxart’s vaccines are administered using a
convenient room temperature-stable tablet, rather than by injection.
Vaxart believes that tableted vaccines are easier to distribute and
administer than injectable vaccines and have the potential to
significantly increase vaccination rates. Vaxart’s development programs
include oral tablet vaccines that are designed to protect against
norovirus, seasonal influenza and respiratory syncytial virus (RSV), as
well as a therapeutic vaccine for human papillomavirus (HPV).
