I remember CH publishing antibody testing early on, but DE data was pretty rubbish, so I don't know what happened.

Excess deaths were higher in CH, but now it's just straight flat.

I just looked at a few other countries. If it weren't for also relatively flat Denmark, I'd say it's all kill-off. Maybe it's that & ability to protect yourself in 65+ groups.
