what vac scene experts on these panels were already noting to media, is that two doses of moderna even if you re high risk seem to be pretty darn good many months out, six months out. so that s why they re saying there s some question do we actually need that booster? but they have decided to greenlight a half dose booster, i think in part for consistency purposes. my mother, for example, got two doses of moderna, wondering when she s going to get the booster. i ve heard something similar. so avoid confusion to remain consistent. recognizing we need to be humble about the uncertainty that lies ahead. i think it was the right move. but that is the reason why that half dose was indicated because those first two doses of moderna were a higher concentration than the first two doses of pfizer. i want to play you something that came out of the fda panel meeting today. this is a pediatrician and noted vaccine expert dr. paul offit. and doc, i ll ask you to interpret what he s saying here on
