Why is there so much excess mortality in 2022 and 2023?

Most countries should have experienced a cumulative mortality deficit since approx. mid-2021 if the vaccines had worked and because of the reversion to the mean after the excess mortality of 2020/2021. — Instead, all show strong cumulative excesses or, at best, small excesses. pic.twitter.com/RNhsxUvmoM

[DS–one of the great unanswered questions is why there has been a substantial increase in the number of unexpected deaths since the COVID vaccine rolled out. The whole point of the vaccines was to reduce deaths from COVID, and indeed deaths from COVID have decreased as one would expect (with or without the vaccine as vulnerable people died). But all-cause mortality has remained stubbornly higher than baseline in most countries. Why? And why is nobody trying to find an explanation?]
