More 18 than 1 million deaths are accounted for relevant pandemic disease COVID-19. Recent data 19 showed that D614G genotype of the virus is highly infectious and responsible for almost all 20 infection for 2nd wave. Despite of multiple vaccine development initiatives, there are currently 21 no report that has addressed this critical variant D614G as vaccine candidate. Here we report 22 the development of an mRNA-LNP vaccine considering the D614G variant and 23 characterization of the vaccine in preclinical trial.
