that, you give it the opportunity to mutate. when it mutates, you can form another variant, which might actually escape the protection of the vaccines. we've been fortunate that the vaccines that we have now vaccines that we have now are doing very well against all the variants including the delta variant. but that could change. and that could change if you get more variants. so people not getting vaccinated are not only potentially harming themselves and their family but they're potentially leading to the creation of more variants. >> and that's the thing. i've been likening it to like the movie "alien," right? where it's one kind of alien, then it morphs into another kind and another kind and they just get more powerful as they morph using the human body as a host. right? it's the same thing. i worry that we're on mu already. lambda i was worried about. now we're on mu. we're just going down the greek alphabet. by the time we get to omega i worry it will be unbeatable.
