there is also this potential tug of war as the south african health minister was talking about this morning as viruses become more transmissible, evolve into becoming more contagious, sometimes they lose some of their punch as well. 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 mutations were associated 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 gives you an idea of what scientists are trying to deal with in terms of identifying --
