Entry rules from February 22, 2022:

A 3-G proof (vaccinated, recovered or tested) is required for entry into Austria. If there is no 3-G proof upon entry, you must register and quarantine for ten days until you receive a negative test result.

Validity of the test results: PCR test 72 hours, antigen test 24 hours.

Children under the age of 12 are exept from the 3G obligation to provide proof. 

Children up to the age of 12 do not need their own G-proof. This also applies to people over the age of 12 who are of school age and have a valid Ninja Pass or Holiday Ninja Pass. After completing the ninth school year, young people, like adults, require a 2-G certificate.

The documents must be issued in German or English. Please also have one of these proofs ready for check-in.
