The thing is, knowledge must come from somewhere. Your knowledge depends on which sources you watch, ask and read. Because from their point of view, they *"know"* that the vaccine may not prevent you from catching covid, but lowers the odds and severity. They believe to know it reduces the time you have symptoms and thus indirectly reduces transmission. They "know" it saved millions of lifes. And if you ask them how they know such outlandish things, they tell you they have their knowledge from their own government. From Big Pharma. From knowing that foreign governments have lockdowns and vaccinate their citizen, like europe and russia. And perhaps from asking their doctor.
