Coupled with the forthcoming CBCDs, this is a real shakedown for the plebs. This has no merit, when the Covid jabs are neither demonstrably safe nor efficacious. They are certainly incredibly profitable, and are being pushed by demonstrably criminal organisations. The utility and other functionality which can combine with this ostensible 'medical' global good is outrageously intrusive and repressive.
Unlike yellow fever, which has an insect vector which carries the disease in certain countries and which seemingly defies eradication attempts, if going to those countries it is advisable to get those inoculations which have years of demonstrable evidence based safety and effectiveness profiles.
The Covid farrago, on the other hand is a con job - and in my OPINION, being utilised as a cover for hoarding of oil & gas resources for the wealthy, with the overall restriction of lower orders in their travel, association, discretionary financial freedom and ability to influence the world around them. Amongst other functionality.

Nobody should entertain this idea.
