Investigators at the National Cancer Institute (NCI) have discovered an adjuvanted mucosal subunit vaccine to prevent SARS-CoV-2 transmission and infection. The mucosal vaccine is composed of a novel molecular adjuvant nanoparticle that induces robust humoral and cellular immunity, as well as trained innate immunity with enhanced protection against respiratory SARS-CoV-2 exposure. The technology is available for potential licensing or collaborative research to co-develop these therapeutic targets.
The development of a vaccine against human immunodeficiency virus (HIV) would be expected to provide long-lasting protection. Researchers at the National Cancer Institute (NCI) developed a high efficacy vaccine and microbicide combination for use in an improved HIV vaccine regimen.
