what about omicron gives you that confidence? what part of it? because there s all these mutations which is obviously freaking out this is a more mutated virus than i guess was expected this early, correct? well, what we ve seen is when you get really very, very high levels of virus neutralizing antibody, when we looked at it against the beta variant that came out of south africa last year, or the lambda which had some of the same mutations as omicron, yes, you got a decrease in virus neutralizing antibody with it but if you had enough to begin with, it seemed to hold you over. there was spillover, i think that s the term dr. fauci used, spillover antibody to cross-protect and that may still be the case even though there are additional variants. and the experiments we need to do to confirm that are not that complicated, so we re doing it in our lab now at texas children s hospital and baylor
