Breakthrough in COVID-19 Vaccine Research: Robust Mucosal Immune Response Against Diverse SARS-CoV-2 Variants

Researchers at Sun Yat-sen University have developed a novel nanoparticle vaccine, FP-HR5-NP, which has shown remarkable efficacy in eliciting robust mucosal and systemic immune responses against diverse SARS-CoV-2 variants, including Delta and Omicron. Administered intranasally, the vaccine triggered the production of high titers of FP- and HR5-specific IgG antibodies, as
