professor, shout me how from the be will center on the center for molecular life science of the university of basil in switzerland. let's clarify the situation in vietnam. first of all, is there a new variant? and if so, how worrying is it? yeah. so what we know from vietnam at the moment is that they, they are observing the very end of the area that caused the big outbreak in india. and some of the genome say they described over the last few days, they have an edition, a deletion that position $144.00 the spike protein. and that is what if, occasionally mutation that you've seen previously, for example, in the very and alpha, the one that originated in the u. k. but that in itself is not really to worry concerning the house in the police, in that position. $144.00 before, all right, and mutations per se, under worrying either as far as i know, they're normal because that is what viruses do in order to survive. so why all the fuss about new variance right now? yes, the wires, this particular aren't a virus. if you take all the time, they have a fairly sloppy replication machinery. that means that t
