not really - only 20% ‘natural’ wild immunity - the rest are ‘natural ‘vaccinated immunity. Another point - immunity from wild covid doesn’t always mean immunity from Delta or the variants as ‘wild’ immunity is exposure-dependent, lower exposure level, less immunity. More exposure that results in hospitalization equals more immunity :)

Empirical studies show that wild or natural immunity makes individuals 27 times less likely to contract Delta variant.

I would say that is robust and vastly superior to vaccine based immunity.

20 percent is also the absolute minimum observed in the blood supply sample. It could be much higher and easily toward 40%.

[Grandpa Drudge]

Exactly right, immunity as a result of recovery from the natural infection is far superior to vaccine induced immunity in 2 ways. Its much stronger, and it lasts much longer (years vs months). And if you believe there might be unexpected long term risks from the vaccine itself (as I do) you might choose to risk the disease rather than the vaccine.

They were just giving advice on the platelet donation. They try to remain neutral given the clientele.
