quite rapidly. the interest would be that is particularly contagious. we don't know about the severity. were trying to collect that data as quickly as possible. >> i'm interested when you talk about spike protein it confuses people when you say various mutation is spike protein. what do you mean by that? >> remember the picture of this virus that has the spikes on the surface which are made up of protein. that's a part of the virus that has to find a receptor receptor on your self to get inside. this one is apparently able to still do that. it's infecting people. but the shape of the protein is different because of the 30 plus mutations so it looks a little different. if you raise antibodies against that for previously being infected were vaccinated, the question is will the antibodies still stick to this version of the spike protein or will they invade that protection.
