Vaccine passports have arrived in many nations in various forms.

This has been a long time coming. It seems like a long time ago now – over a year ago – when Bill Gates started mouthing off about the need for immunity certificates and digital vaccine passports. The plan is not hidden, but rather wide out in the open. Of course, there is a distinct lack of logic about the whole issue. First of all, as I have exhaustively documented, there is no evidence that the virus SARS-CoV-2 exists. But putting that inconvenient truth aside for a moment, why couldn’t natural immunity to the virus qualify you for the vaccine passport? Mainstream brainwashed medical authorities may say it’s because you can still get re-infected. However the same goes for the vaccine … hence all the talks of a 2nd and 3rd shot (actually the plan is to give people countless shots as they upgrade and rewire their DNA operating system). This is the very same group of vaccines which by the way don’t give you proper immunity and are even admitted to only protect against mild symptoms and not to stop transmission.

It’s not about actual real immunity to disease. It’s about finding out who is vaccinated and who is unvaccinated, and subsequently punishing the non-compliant, disobedient, recalcitrant unvaccinated ones.
