NIAID scientists led the animal study with colleagues from HDT Bio in Seattle who developed the replicating RNA vaccine (repRNA) platform. The findings also suggest that the HPAI H5N1 circulating in the U.S. may be able to evade immunity from older H5N1 viruses. The scientists continue to develop the repRNA vaccine platform, and evaluations in additional animal models are ongoing.   National Institute of Allergy and Infectious Diseases  |  National Institutes of Health Update your subscriptions, modify your password or e-mail address, or stop subscriptions at any time on your Subscriber Preferences Page.
