Poster on the forum 4chan (origin of Q), in September of 2019, before COVID had been heard of, gets too many of the precise details correct for it to be coincidence. Refers to himself as "operative".
1) virus would be released in Winter 2020
2) would be deadly to elderly, but the it would be hoaxed that it's deadly for everyone
3) jab would be the real killer
4) jab contains toxic metals
5) would be released in a "Market"
6) would hit the US in a West Coast state (patient zero was from Seattle)
He did get one piece wrong, that it would be deadly to babies also (in addition to the elderly).
He predicts that 9-10 million American would die (didn't give a timeframe).https://rumble.com/embed/vpspxh/?pub=4
