"If a 93-year-old man who was diagnosed with CHF five years ago dies after getting the vaccine, his doctor has to report it. Even if he would have died anyway."

In the example, the old gentleman did not die of Covid. He died of heart failure after getting the vaccine. Whether the vaccine had anything to do with his death is a question. He may have died that day anyway, considering his longstanding disease. Or he may not have. Either way, it must be reported.
