better sense of why the fda decided to delay moving forward with a covid vaccine authorization for children under 5 years old. dr. scott gottlieb, former fda commissioner and current board member for pfizer says the decision was not because of any safety issues regarding the shot, but instead, about defining its level of efficacy amid an ongoing trial involving a third vaccine dose. given the fact that that is changing, that s evolving, new data is accruing, it s hard for the fda to give its advisers a fixed snapshot of what the absolute efficacy of this clinical trial of the data set. so if they wait a little longer, if they administer the third dose in that clinical trial, they re not only going to have a better measure of effectiveness from this trial, they ll also have a settled data set, a firm picture of what level of effectiveness the vaccine is delivering. the fda s vaccine s advisory
authorization for the vaccine for children, and it s about finding the level of efficacy amid a ongoing trial involving a third dose of the vaccine. given the fact that that is changing, that s evolving, new data is accruing. it s hard for the fda to give its advisers a fixed snap shop what of efficacy, so if they wait longer and administer the third dose in that clinical trial, they will have a better measure of the effectiveness, but they will have a very firm picture of what level of effectiveness the vaccine is delivering. across the united states, hundreds of thousands of vaccine doses are being administered daily, but so far cdc data shows less than 30% of the u.s. population has received the third shot, the booster shot. meantime hong kong is reporting more than 1,300 new covid
nation, he s also a pfizer board member. take a listen. given the fact that s changing, that s evolving. new data is accruing, it s hard for fda to give a fixed snapshot of what the efficacy of this clinical data set so if they wait a little longer, if they administer the third dose in that clinical trial, they re not only going to have perhaps a better measure of effectiveness from this trial, but they ll also have a data set, a firm picture of what level of effectiveness the vaccine is delivering. and that wait, we might have to wait until april. pfizer said it could have data on its three dose vaccine series in early april. just a couple of months away, it s all about the efficacy, and not the safety. jacqueline howard, thank you so much. and still ahead, a former white house adviser who navigated russia s last invasion of ukraine warns that the u.s. cannot underestimate vladimir putin again. we ll speak with her live up next. m driving, i see inspiration right through my
they re trying not to let russia get too isolated, but i think even the chinese understand it is not in their interests to blow up the international order and to blow up the international economy, especially when letting putin twist in the wind as he is doing now is actually to china s advantage. no matter how this ends, excuse me, this is going to end with a much weaker russia that s going to be somewhat dependent on china. putin has made one of the greatest strategic blunders of the past 50 or 60 years, and that s to the advantage of china. so i don t see where china, unless i m misreading xi somehow, i don t see where it is to china s advantage to play hardball with the white house because putin s mistakes are all accruing to the advantage of a stronger china and a weaker russia. noah, we need to go to break, but i just want to read this to you and get your reaction.
you are restricting trade with another country, so you will be affected yourself. yes, of course you will. but there s also a whole other generation of sanctions where you can focus your sanctions on individuals, and that has a much greater effect on those individuals and everyone else. when it comes to the putin regime, so many of these oligarchs are close friends of putin s, and they have his gold in his pockets. he doesn t keep his money abroad in his own name, he keeps it in the name of others so clamping down on them is also a pretty good way of clamping down on putin. ., ., , , . ., , , putin. tom keating specialises in financial crime putin. tom keating specialises in financial crime and putin. tom keating specialises in financial crime and internationall financial crime and international consequences of some of this, and he said earlier that this is all fine, but in the end until you deal with money that s accruing to the russian states their oil and gas sales, all of thi
