Figure 3. Comparison of the antigenic residues of VP7 present in genotype G1 strains of RotaTeq and Rotarix, and the strains circulating in Bhutan.

The respective antigenic epitopes are shown above the residue numbers. The amino acid residues in the Bhutanese strains that differed from those in the vaccine strains are highlighted in blue. The amino acid residues highlighted in yellow indicate that the residue is different from the other vaccine strain and Bhutanese strains.
