Vaxart: Funding, Investors & Team (Oct 2026)
Vaxart is revolutionizing the field of vaccines by introducing oral vaccine pills. Unlike traditional vaccines that are administered through intramuscular injection, our pills target the mucosal areas of the body such as the mouth, nose, and gut where pathogens enter. By doing so, they induce powerful IgA and T-cell responses to effectively combat and overpower viral invaders. Vaxart has already commenced Phase II trials for its oral vaccines against Covid and Norovirus, making it the sole company worldwide to reach this stage with a COVID-19 vaccine in pill form.
Vaxart has raised $40.0M across 2 funding rounds on record, the most recent an undisclosed round of $25.0M announced in Apr 2026.
That round is above the $8.4M median round size for Biotechnology companies tracked on FundedIQ over the last two years.

About FundedIQ's Vaxart Funding Data
FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.
Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Vaxart is left off this page rather than filled in.
