It will happen; the technocrats such as Bill Gates and friendly elves at the World Health Organization have said that there will be a new pandemic, this time with a virus with real teeth that will scare the pants of the population. As everyone has Covid fatigue, it will need to be something truly horrible with a high mortality. Bird Flu would fit the bill, being only a mutation or so from infecting humans, but a lab leak would solve that. Then there is Marburg virus disease, which is a haemophilic fever, and something that has featured in various movies, very much a zombie apocalypse. That would meet the agenda too, and the case would be put for compulsory vax too, under the World Health Organization pandemic treaty, if it is not defeated.
My guess is that this plandemic will be rolled out in 2024, so the US gets postal voting and massive electoral fraud once more to topple Trump, once more.
