Again, when were talking about scaling back our measures of prevention of infection, when were talking that in a setting of when we know we have waning efficacy with the two doses and even if you have a booster, studies are showing by ten weeks out. i got any booster shot in september. by 10 weeks out, 30 % to 50% efficacy with that vaccine. and we may have b-cells and t-cells involved, but the question is do we want to risk that? do we want to risk infection of a virus when we dont know the lon...

Our aim should be to prevent severe disease, hospitalisation and death. Our aim should not be to prevent mild respiratory disease with scratchy throats.

Are thinking you are making the right decision by getting your kids vaccinated, and there still could be school closures. this is from fara, is the booster still effective for omicron? >> the answer is we dont know yet because we only have booster data out four weeks for pfizer and two weeks for moderna. that is antibody levels, four weeks after a booster, and in the case of moderna, four weeks after the booster. if we all talk about this, its a three-shot series, its a three-shot series, what d...

Company look at the data. it is encouraging that a third dose increases the antibody response. its not clear to me yet that thats something thats really going to be necessary. when you think about the immune response that we have, its a pretty incredible thing. one piece of it is the antibodies that theyre measuring in the blood. the other piece of it is call cellular immunity, and thats done by your b cells and your t cells, and those are designed to be able to protect you from viruses that loo...

Going to be necessary. when you think about the immune response that we have, its a pretty incredible thing. one piece of it is the antibodies that theyre measuring in the blood. the other piece of it is call cellular immunity, and thats done by your b cells and your t cells, and those are designed to be able to protect you from viruses that look like viruses youve seen before. it may be that even with a lower level of antibodies, your body once it sees the omicron variant will kick up, generate...

Damage. to the point about the vaccine. i want to make an important point this has been a hyperfocus in the media on neutralizing antibodies that we track to see how well the vaccine is working. from are t-cells and b-cells. thats what your body remembers from the vaccine. it amps up when it sees the virus and produces more antibodies that go for the variant. thats why you are seeing mild breakthrough cases. i am for the booster shots but if you are vaccinated or over covid and got a vaccine you...

Previewed, that showed that there was 40 times less likely to be protected from the vaccine with omicron, then -- than with delta even, that of course is a worrying piece of information to hear, especially driving in your car. but it is a potential problem. however, we still believe that the vaccines will prevent, as i was saying earlier, serious disease and deaths. and dont forget the one thing people should remember is that what theyre measuring in these little research studies right now that ...

Big picture, the global impact, the 60 million or so americans who are still unvaccinated. for those of us who have been following the science and following the recommendation, i think that we all can still feel reasonably in control of this, which, you know, might sound a little bit, you know, sort of in contrast to the messaging about the variant, but listen, people really do need to understand that vaccination plus boosting really does in all likelihood confer a significant amount of protecti...

That theres no evolutionary advantage to a virus to become more severe, because it will die off with the host it infects. so what i suspect we are going to hear in a matter of weeks is that it is more contagious, to what degree i dont know, and probably evades immune protection from vaccination, again partially. to what degree, we dont know. but i want to reiterate and remind everybody out there, if youll indulge me for a second, the way the immune system works, if there is a blunted antibody re...
