Vaxart Announces Publication in Vaccines of Non-Human Primate Preclinical Data Demonstrating Its Next-Generation Vaccine Candidates Elicit Mucosal and Systemic Immunogenicity and Reduce Viral Shedding after SARS-CoV-2 Challenge
SOUTH SAN FRANCISCO, Calif., Feb. 05, 2024 (GLOBE NEWSWIRE) -- Vaxart, Inc. (Nasdaq: VXRT) today announced the publication of preclinical non-human primate data demonstrating the potential of its COVID-19 vaccine to protect against multiple SARS-CoV-2 variants of concern (VOC)s. The data, which were previously presented at the International Congress of Mucosal Immunology 2022, are reported in the current issue of Vaccines.
- “The data published in Vaccines support the potential of our vaccine platform to stimulate potent mucosal cross-reactive IgA responses to multiple VOCs and reduce viral transmission.
- All three vaccines induced neutralizing antibodies in both the peripheral and mucosal compartments, which was enhanced with a boost immunization.
- Viral replication and infectious particle shedding were significantly reduced in immunized animals after challenge with beta variant SARS-CoV-2.
- Vaxart believes these data support the potential for its vaccines to enhance mucosal responses and reduce community transmission, in addition to preventing severe disease.
