EMERYVILLE, Calif., Aug. 20, 2021 /PRNewswire/ -- Amyris, Inc. (AMRS), a leading synthetic biotechnology company active in the Clean Health and Beauty markets through its consumer brands, and a top supplier of sustainable and natural ingredients, today announced promising in-vivo results in a study of its licensed RNA vaccine through intranasal delivery, developed in collaboration with the Infectious Disease Research Institute (IDRI).

Current mRNA vaccine technologies are providing limited immunity protection for the upper respiratory system. As a result, vaccinated people may experience viral replication and viral shedding regardless of variants. 
In-vivo results indicate that, when delivered to the mucosal membranes via intranasal administration, the Amyris/IDRI RNA vaccine generates antibodies and provides upper respiratory protection for SARS-CoV-2 (COVID-19), which Amyris believes has the potential to provide fuller protection against current variants of SARS-CoV-2. The Amyris/IDRI RNA technology may also support the potential for intranasal vaccine delivery that can protect against SARS-CoV-2 and other respiratory diseases, including the flu.
If approved and commercialized, the Amyris/IDRI RNA vaccine is targeted to be more accessible to people in underserved countries. In addition, the intranasal vaccine may offer improved upper respiratory protection beyond currently approved vaccines.  
"Amyris is committed to developing and delivering the most affordable and best performing protection against SARS-CoV-2 and other respiratory diseases," commented John Melo, President and Chief Executive Officer. "Our previously announced collaboration with Nant Africa, LLC is advancing to human trials in South Africa and includes them funding human clinical trials, which upon successful completion and approval, are expected to be followed by the production and scaling of the vaccine in South Africa as early as next year. With these new in-vivo results, we are exploring a simple nasal delivery system for our RNA vaccine, which we believe has the potential to provide much needed upper respiratory protection against SARS-CoV-2. We are working diligently to prove the effectiveness of our RNA technology and drive speed to market."
Amyris will provide a detailed update of the progress of its vaccine platform and a roadmap for scale up and delivery during one of its upcoming investor mini-series webinars.
