Some speculations
[forbiddenknowledgetv.net]
I've been saying the same thing on this platform. The "vaccines" are not working as fast as the designers had hoped to kill off most of the Earth's population of humans. Hence, they started in with boosters. When you get a booster shot for any other virus they have put parts of the mutated form of the virus into the jab. These so called "boosters" are just more of the same crap as the original jab. They want you dead and you are cooperating in your own eradication by accepting the jab.
