The 2019 coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), is in the midst of a pandemic and threatens global public healthThe prevention and control of COVID-19 is in urgent need of vaccine developmentHere, researchers from several research institutions in China reported the experimental scale production of an inactivated SARS-CoV-2 vaccine candidate vaccine (BBIBP-CorV)The vaccine induces mice, rats, guinea pigs, rabbits and non-human primates (canine and macaques) to produce high levels of neutralizing antibody titer to provide protection against SARS-CoV-2two doses of immunity using 2 micrograms/dose of BBIBP-CorV, which can efficiently protect macaques from SARS-CoV-2's trachea challenges without detecting an antibody-dependent infection enhancementin addition, BBIBP-CorV demonstrates efficient productivity and good genetic stability and can be used in vaccine productionThese results support further evaluation of BBIBP-CorV in clinical trials
