Seems to be about face to the earlier COVID era which was highly lethal to oldies. Back then it there was a lack of medical knowledge and drugs to deal with it.
Now we see oldies with light or no symptoms and youngies with nasty symptoms. Could be down to the dose/viral load. If you get a tiny dose perhaps your vaccinated immune system can defeat it before it gets established, but a large dose gets ahead of your defenses?
I know of one elderly (90+) person unvaccinated who has just had Covid. They didn't know they had it until they were tested during a surveillance test. They ended up with a few symptoms but it wasn't all that bad and have made a prompt and full recovery. The isolation had a bigger impact than Covid did.
