AbstractThe recently emerged coronavirus SARS-CoV-2, the causative agent of COVID-19, is rapidly spreading in theworld with over 4,8 million cases, and 320,000 deaths as of May 16, 2020. This novel coronavirus is thought tohave emerged from a live animal market in Wuhan, China. It has quickly spread in the community with largeclusters of human-to-human transmission. Sequencing of several isolates has determined that the most closelyrelated strains are SARS-like bat coronavirus lineages. The susceptibility of SARS-CoV-2 to anti-viralcompounds, its ability to replicate in cell lines or host factors regulating its replication are all currently unknown.Importantly, there are no therapeutics available to treat the virus, although investigational studies are underway.Modelling of the current outbreak suggests that the virus could infect >1 billion people and become a yearlyepidemic. Identifying people who have developed antibodies is important for the epidemiology as well as patientcare.With the exponentially expounding threat of SARS-CoV-2 to global health, a vaccine is desperately needed.Herein we propose the development of a novel, highly efficacious and safe COVID-19 vaccine with facile scaleup potential. Our proposal uses a rabies virus-based vector that has proven to be an efficient vaccine againstemerging and re-emerging infectious diseases. We have demonstrated that inactivated rabies virus particlescontaining the coronavirus (CoV) spike S1 protein induce potent immune responses and provide protection inanimal systems against Middle Eastern Respiratory Syndrome coronavirus (MERS) and Severe AcuteRespiratory Syndrome (SARS) coronavirus, both of which are highly related to SARS-CoV-2. A similar vaccineentitled CoraVax™ is available and herein we propose to analyze CoraVax™ immunogenicity in mice as well asits abilty to protect in a hamster model.
