We've been hearing this for a while, but I don't think there's going to be some Oscar-worthy worldwide day where everyone just starts dropping where they stand. I believe there are exceptional long term consequences for the vaccinated to the point that we may see a massive drop in life expectancy over the next 50 years, but as is typical of government, they'll try to hide the truth while it's as plain as the nose on your face.
They will explain it away for as long as they can, until all pertinent parties cannot be held accountable.
