The Phase 2 study was completed with support from Biomedical Advanced
Research and Development Authority (BARDA). Vaxart received a $13.9
million contract from BARDA in September 2015 to support the advanced
development of more effective influenza vaccines to ultimately improve
seasonal and pandemic influenza preparedness. The contract was increased
to $15.7 million in 2017.

The project has been funded in whole or in part with federal funds from
the Department of Health and Human Services’ Office of the Assistant
Secretary for Preparedness and Response; Biomedical Advanced Research
and Development Authority under Contract No. HHSO100201500034C.

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). For more
