It won’t work, better to get an original paper from a third world country. As I wrote in this and another thread, wait till tourism will open again, sooner or later EUSSR︀ will have to accept people vaccinated in free countries and bam, you’ll show your 100%︁ original vaccine certificate - no dark, no forged, but issued by some health minister.
In the meantime, keep making PCR tests, they are useless but harmless. (possible problem if you︂ are eussr citizen, they could/will ask you why you took the jab outside eurocage, that’s︃ why it is more and more important being a resident of an offshore country).
