NIH Dangles West Nile Virus-Busting Antibodies for Licensing Deals
Published Date: 4/22/2026
Notice
Summary
The National Institutes of Health is offering licenses for new human antibodies that can block West Nile virus, a mosquito-borne illness with no current vaccine or treatment. These antibodies could help protect or treat people at risk, especially older adults and those with weak immune systems. Companies interested in developing these therapies can apply now, with some foreign patent protections available to boost market reach.

NIH Licensing Opportunity for Companies
The NIH is offering a license (HHS Ref. E-021-2026-0) for seven fully human monoclonal antibodies against West Nile virus (AIS-196, AIS-204, AIS-259, AIS-260, AIS-261, AIS-262, AIS-265). A provisional patent (No. 63/991,485) was filed on February 26, 2026, and foreign patent applications on selected inventions may be available to extend market coverage. Companies or parties interested in commercial licensing or collaborative research can contact Brian Bailey at 240-669-5128 or [email protected].
Potential New Protection for Older Adults
Researchers identified seven fully human monoclonal antibodies that strongly block West Nile virus infection and showed protective effects in mouse studies; these could be developed to prevent or treat disease for people at higher risk, especially older adults and people with weakened immune systems. There is currently no approved human WNV vaccine or specific antiviral treatment, so these antibodies offer a new prevention or treatment path starting from pre-clinical development.
Antibodies Available for Diagnostics and Surveillance
The antibody sequences and production tools are available for licensing to produce high-quality reagents for West Nile virus testing, diagnosis, surveillance, and research. Public health laboratories and researchers could license these materials or collaborate with NIH to support WNV detection and monitoring.
