Nice one here. You guys are right, it gets worse for the animals with evolution. It adapts to us faster than we can adapt to it, if you get what I'm saying.
Yea, it gets worse for the mice. You know an animal it probably doesn't get worse in? Bats. They have interferon signaling to deal with this kind of nasty virus
This was a tough question and requires thinking in a partially complex system
On Average, immune memory will dampen severity of a reinfection
So if you get reinfected with a more pathogenic variant it may appear less severe. But with time can decompensate
Nice job
Yea, it ended up killing every young mouse it infected after 15 generations of passage
Looks like it was able to adapt to execution of its programs optimally which were incompatible with the host
Remember, cov2 has a program its trying to execute
So the question about reinfections with more virulent variants- immune memory can compensate a bit to make the reinfection less severe. However elderly can decompensate, their immune systems are not as fit. I wonder if omicron is putting kids in hospital more frequently.
All in all it seems you guys do very well with the knowledge. B+
And way better than the people with wishful thinking!

Hey guys. A lot of T cell hopium being irresponsibly passed around
I'm not cosigning that. If a mild case of Covid is giving lung diffusion issues, and given there is no published t cell correlate of protection, I think it's irresponsible and also disingenuous to write
Imagine I came to your field and said, "oh yea B cells will ramp up and protect you" if you were a researcher showing B cells were producing autoantibodies and producing severe cases.
You'd say, "wait a gosh darn minute, In some people that works to the opposite"
T cells are not some incantation you can invoke which will separate you from severe disease. Very sick people have the t cells
There's also no published correlate
there is no t cell marker to show who is a 30 year old that will get severe vs. mild illness based on their t cells
