Unfortunately I only got as far as the headline before I was asked to create an account and I don’t want to do that. Anyway the article appears to be saying that it’s down to genetics. I don’t really know how that can be as coronavirus is a novel virus, so humans have no immunity, well had no immunity when it was first identified. But I’m not a scientist so I know nothing.
I hope that research will enlighten us about this as I'm sure this has a basis in fact.
There are people in this country, seemingly healthy who have succumbed to Covid quite rapidly and become very ill, as you yourself know. Then I know people who have been very ill indeed with other illnesses including cancer, who have caught Covid and had mild or no symptoms at all, even before there was a vaccine.
