The global IFR was claimed to be around 3% and CFR around 10% in early 2020 because of how the tests were restricted, artificially reducing the denominator. I think serious side-effects were claimed around 40-50% as well, but not sure I'm remembering that one right. It was never actually that high, but most people had no idea what was actually going on and it caused all sorts of panic which led to the lockdowns.
