We may welcome guests (as of 24. December 2021) who meet the 2G rule. If you are vaccinated (valid for 270 days from second or third vaccination) or recovered (not longer than 180 days from recovery!), you are welcome!
When returning to Germany, you as a vaccinated person only have to submit a digital entry declaration up to and including 24. December 2021. However, you do not need a PCR test, nor a quarantine. This affects “only” unvaccinated children under 12 years and lasts 5 days. As of 25. December 2021, Austria is no longer considered a high-risk area for Germany, so both entry registration and the quarantine requirement can be waived.
