looks like ETIAS 'beast system' (European Travel Information Authorization System) may be ushered in with a must vaccination certificate as early as 2021. No vac, NO travel.
Thuringia in Germany Abandons Virus Restrictions
excerpt:
We have reliable rumors behind the curtain coming from Europe that beginning in 2021, all foreign citizens will be required to undergo a pre-screening and registration process, which will be known as the European Travel Information and Authorization System (ETIAS) before entering European Schengen-zone[2] countries. Not all EU members are part of this Schengen agreement – notably Britain, Scotland, and Ireland. While this system was on schedule before the coronavirus, what is being suggested is that this should now include a health certificate to prove you have been vaccinated to visit Europe by Bill Gates. If there is one way to kill tourism in Europe, they seem to have discovered that perfect law.
