Schematic of the study strategy. A Mutations in the spike of B.1.1.7 (Alpha) and B.1.351 (Beta) involved in this study. B The position display of substitutions or deletions in B.1.1.7 (Alpha) and B.1.351 (Beta) spike structure. C Immunization strategy and experimental schedule. Mice were primed and boosted on weeks 0 and 3 with DNA immunogens, including all the single mutation-containing variants and the D614G, B.1.1.7, and B.1.351 lineages
