Can the federal government force certain professional groups to have corona vaccinations? Bavaria’s Prime Minister Markus Söder is in favor, the Ministry of Defense is also examining such a step, Federal Health Minister Spahn has so far been against it. An alternative to compulsory vaccination would be advantages for vaccinated people. Federal Foreign Minister Heiko Maas recently demanded that they should be allowed back to cinemas and restaurants earlier than others. But this proposal also met with a lot of rejection. Stephan Noller’s company Ubirch has built a technology for digital vaccination and test records. The company’s certificates generated in the doctor’s office are stored on blockchains on the Internet and accessed using a QR code, for example. Noller believes the debate will calm down and vaccination records will soon be normal.
