they trade one off for the other. so you may sigh that. in terms of what we know, this is, again, unfolding real-time. the specimen that was collected that ended up being the first specimen that was on november 9th so, you know, just three -- three weeks ago or so. and it was identified to have this genomic sequence. we now know it's in 15-plus countries around the world and there's some 50 mutations on this. some of these mutations, we have seen before and they were associated with more transmissibility. other my tutations were associa with a higher chance of escaping the immunity. i don't know if we have a 3d image we can just show this real quick. if we have it, you can see the spike protein of this virus and you can see all these various mutations on it. and it gfives you an idea of wht scientists are trying to deal with in terms of identifying -- that's it. the spike protein and these are the mutations with this particular variant. that's -- that's the 3d representation of what they are basically trying to deal with and address, anderson. >> i don't even know what i am
