It's already been several months. Also, vaccination in China, India, Nigeria and other very populated countries is lagging behind. If you want to depopulate, you'd make sure they are keeping pace. As of now, you'd end up with small rich countries dying like flies before the populous countries are even 50% first jab. The timeline doesn't work at all. It would need to be a year or more before mass death occurs, but that comes with a set of problem as well. The dying would be too spread out. That's a long ass time for people to find about it and find something that neutralizes it. Also, if people learn about it, they have quite a while to go berserk on those who pushed the jab. Maybe you are banking on the jab needing an instigating event to then kill them within months. Maybe a second jab that creates a reaction; same deployment problem as the first jab. A second cold/flu pandemic; after a year and a half, only (let's be very generous) 500M people have gotten it and with an increase mortality rate, comes a diminution in transmission. It wouldn't work. If you want to logically depopulate the world, kids get tons of jabs, make them infertile with one of them. Then you have about 16-17 years before shit hit the fans. Then find your favorite theory; 5g, microplastic, etc. propagandize the hell out of it and blame it for it. Make a big fuss about getting rid of it, creating your massive socio-economic change. The possibility of artificial womb and artificial sperm is there, but it's not that hard to keep track of that and buy them out as they come along. Mass death isn't very logical.
