These mutations are in the area that binds to human cells. that is what is extremely important for the immunity, so one paper, you might think that the vaccination might work less against this omicron variant, but the proof is a meeting of the pudding and in a couple of weeks we will know for sure. we are seeinu weeks we will know for sure. we are seeing different _ weeks we will know for sure. we are seeing different countries _ weeks we will know for sure. we are seeing different countries react - weeks we will know for sure. we are seeing different countries react in i seeing different coun...

Originating. we begin with the latest from atlanta and correspondent jonathaner isry. >> the world health organization identified the threat and gave it the name omicron and identified ate as variant of concern. >> what we do know is this has a large number of mutations and the concern is that when you have so many mutations, it can have an impact on how the virus behaves. >> both mutations include multiple changes to the spike protein, the part of the virus that penetrates human cells. researchers are still determining the threat, omicron's threat through southern africa concerns the british ...

Other than there are over 50 mutations and 30 on the spike protein that the virus attaches to human cells. the nature from what we have seen can do a couple of things. one is increasing transmissability. if you have it, you are likely to pass it on to somebody else. there is concern the way the few mutations look, it is similar to others. there is a concern that none of the other mutations, beta and lambda have taken over is delta is king of the hill. if you all of a sudden are seeing variant that has mutations that may both cause greater transmissability, but also decrease efficacy of the cur...

They've seen so far. so what do we know about the new variant? well it is early days ? the new variant was discovered just 3 days ago genetic analysis shows it has twice the number of mutations as delta, the dominant variant worldwide, including around 30 changes to the spike protein which the virus uses to break into human cells. this makes it dramatically different from the original wuhan strain on which all current vaccines are based. crucially there is no evidence yet that the variant causes more severe disease or that it makes vaccines less effective. it will take two to three weeks befor...

About the new variant? well, it is early days 7 the new variant was discovered just 3 days ago. genetic analysis shows it has twice the number of mutations as delta, the dominant variant worldwide, including around 30 changes to the spike protein which the virus uses to break into human cells. this makes it dramatically different from the original wuhan strain on which all current vaccines are based. crucially there is no evidence yet that the variant causes more severe disease or that it makes vaccines less effective. it will take two to three weeks before laboratory tests can show whether th...
