<< "which is why this virus will never be fully gone." >>
So, if we don't tamp this virus down as much as we can and as soon as we can, does it have the capacity to mutate into into a much more virulent version? Wouldn't that be a blast. A highly contagious virus that becomes very lethal too. Talk about chaos and pandemonium.
A quick Google search doesn't seem to provide a good answer. I don't see anything saying that possibility has a low probability. You would think that we all should have learned a lesson over the past year.
Is it likely to do that no matter what we do? Just how many "variants" are there going to be over the next year or two? I can't help but think of here what we go thru with the flu shots every year. You never really know until flu season is in full swing whether the vaccine is going to be 10% effective or 60% effective.
I don't think I have ever seen 90% effective for flu vaccines as is being claimed for the new vaccines. Is that because the new ones are not really vaccines in the traditional sense? I.E. exposing the body to a dead or weakened pathogen, then the bodies normal immune system takes over and develops a response to this virus which it can from then on recognize.
I don't know the details with the new stuff, other than most of them(inc. J+J?) work somehow with messenger RNA. Which contain the instructions cells need to make a piece of the spike protein but not the fully functioning COVID-19 virus. So, vastly different than anything we have ever seen before. Maybe that is what accounts for the 90%? But how will that work with all of these variants that are bound to be coming along? Who knows, fingers crossed, but there are also bound to be flat out new viruses coming along in the future. Just like Covid-19 was a new threat to humans starting just 18 months ago. And hopefully we won't- now that Covid-19 threat seems greatly diminished, we won't soon be seeing a bad flu season that might take out 60 or 70K of us, even with traditional vaccines available. We live in interesting times.
