Abstract
The effectiveness of early COVID-19 vaccines in reducing the severity of the disease has led to a focus on developing next-generation vaccines that can prevent infection and transmission of the virus. One promising approach involves the induction of mucosal immunity through nasal administration and a variety of mucosal vaccine candidates using different platforms are currently in development. Live-attenuated viruses, less pathogenic versions of SARS-CoV-2, have promising features as a mucosal vaccine platform and have the potential to induce hybrid immunity in individuals who have already received mRNA vaccines. This review discusses the potential benefits and considerations for the use of live-attenuated SARS-CoV-2 intranasal vaccines and highlights the authors' work in developing such a vaccine platform.
期刊介绍：
Current Opinion in Virology (COVIRO) is a systematic review journal that aims to provide specialists with a unique and educational platform to keep up to date with the expanding volume of information published in the field of virology. It publishes 6 issues per year covering the following 11 sections, each of which is reviewed once a year: Emerging viruses: interspecies transmission; Viral immunology; Viral pathogenesis; Preventive and therapeutic vaccines; Antiviral strategies; Virus structure and expression; Animal models for viral diseases; Engineering for viral resistance; Viruses and cancer; Virus vector interactions. There is also a section that changes every year to reflect hot topics in the field.
