well, as i m beginning to understand it, it s not as much the sheer number of mutations. it s where those mutations are, what those mutations do. what insight are you gaining into that at this point? well, i mean, we know some of these mutations. like you said, it s kind of a frankenstein, so we ve never seen this constellation of mutations before or this number of mutation, but we ve seen those guys in other variants and in viruses that were subc subcritical, right, so we ve seen evolution events in south africa which we re monitoring and similar mutations were there as well. we more or less know what those guys are capable of. you re in the midst of more experiments with omicron samples. what are you focused on right now, alex, in terms of
