COMPOSITIONS IMMUNOGENIC AGAINST SARS CORONAVIRUS 2, METHODS OF MAKING, AND USING THEREOF
Live attenuated viruses for protection against the novel coronavirus which emerged in Wuhan, Hubei Province of China, designated as Sars-CoV-2 by the World Health Organization (WHO) are provided. The live attenuated chimeric virus strains are based on a live attenuated influenza virus (LAIV), used a master backbone, which includes deletion of the viral virulence element, the NS1 (non-structural protein 1) (DeLNS1), engineered to express one or more antigens of the Sars-CoV-2 (herein, CoV2Ag). The chimeric virus strain is referred to generally herein, as DelNS1-Sars-CoV-2-CoV2Ag. The DelNS1-Sars-CoV-2-CoV2Ag strain preferably shows spontaneous cold adaption with preference to grow at 30-33° C. The DelNS1-Sars-CoV-2-CoV2Ag strain can be used to protect a subject in need thereof, against a challenge of Sars-CoV-2. DelNS1-Sars-CoV-2-CoV2Ag is an important strategy for making highly attenuated and immunogenic live attenuated vaccines with the ability to induce protective immunity against Sars-CoV-2..
