Since Sunday, November 14, adjusted travel regulations apply between Germany and Austria. From this date you need a 2G proof (vaccinated or recovered) for your journey home to Germany, as well as a confirmation of the simple but necessary registration at www.einreiseanmeldung.de. For vaccinated & recovered persons there is no quarantine obligation by this.
Children over 12 years of age must also have a 2G certificate. If this is not available, a ten-day quarantine with the possibility of free testing from the 5th day is necessary. For children who have not yet reached the age of twelve, a quarantine of 5 days applies.
