Figure 3

SARS-CoV-2 protein similarities with Mycobacterium tuberculosis (Mtb). Note that BCG, unlike the vaccines in Figure 1 and Figure 2 that are composed of one to seventeen proteins, is composed of 3993 proteins, so that even given the somewhat larger number of significant similarities displayed here, the probability of them being major antigens is extremely small. Note also that because of the size of the BCG proteome, BLAST (rather than LALIGN, as in Figure 1 and Figure 2), was used to find these similarities, and a cut-off value for significance of E = 1.0 rather than 0.1 was used.
