Amino acid variability of the SARS‐CoV‐2 spike protein. Shannon's entropy (H) values for each amino acid position calculated using 10,000 SARS‐CoV‐2 spike proteins are shown. B cell predicted epitopes and T cell predicted epitopes are also reported in blue and green, respectively. B cell epitopes identified in the sera of COVID‐19 patients (Farrera‐Soler et al., 2020; Poh et al., 2020) are also reported in red
