Effectively against this particular variant? to be honest. _ particular variant? to be honest, we _ particular variant? to be honest, we don't - particular variant? to be honest, we don't know. | particular variant? to be i honest, we don't know. we particular variant? to be - honest, we don't know. we see that there are a lot of mutations in these mutations are in an extremely important area of the virus, that is where the virus binds to human cells, and that is what is extremely important for the vaccine immunity. on paper, you might think that the vaccine might think that the vaccine might ...

Level of watchfulness that can be designated bit world health organization. but in addition to that, there's at least 40 mutations on this, on a particular protein in the virus. and the protein that we're concerned about is the one that makes it attach more easily to human cells. and potentially makes it spread more. and i think those are things we're obviously concerned about. but maybe the biggest thing that has investigators and officials worried is the fact that the vaccines that are currently available may not be as effective with omicron as they are with the other variants of the coronav...

What do we need to know about the omicron variance? is it more contagious, would lead to more severe disease? your thoughts? >> those above right questions. it's early enough to be sure we know the answers. that's what a lot of us are spending our time on over the last three days. i've been on zoom calls and phone calls pretty much continuously. we know this is a variant that has a lot of mutations. like 50 of them and more than 30 of those in the spike protein which is a part of the virus that attaches to your human cells if you get infected. that is a new record in terms of the number of mut...

They would have also included working from home and vaccine passports and they did not go as far as that today. boris johnson passports and they did not go as far as that today. borisjohnson said it is about trying to slow the spread, buying time, trying to contain this new variant and where current measures have been enough to hold delta, with this new variant, the worry is that it can spread more quickly and that re— infections can happen even if you are double vaccinated. so, they are buying time for the scientist to carry out more work in the laboratory and also gathering real data to un...

Faxing passports, they didn't go as far as that today. borisjohnson has said it is about trying to slow the spread, buying time, trying to contain this new variant and we are current measures have been enough to hold delta, with this new variant, the worry is it can spread more quickly and that re—infections can happen even if you are double vaccinated. they are buying time for the site is to carry out more work in the lab and gathering more real—world data to understand how this variant behaves because it has got so many more, double the amount of mutations delta had, and they have focuse...
