Required is not recommended: the first is what the border asks about, the second is what a clinic would suggest. Both, for Austria, then the number to dial and what care costs a visitor. Applies to every guide in Austria: Hallstatt, Vienna, Salzburg, Kitzbühel, St. Anton am Arlberg, Innsbruck and 6 more.
Required to enter
Nothing. No vaccination certificate is asked for at the border.
Recommended
Routine vaccinations up to date
Tick-borne encephalitis — Austria has one of the highest rates in Europe and the vaccine is routine for residents
Emergency number
112, or 144 for an ambulance
Care for visitors
Excellent and cheap
EU/EEA and Swiss visitors are treated on the same terms as residents with an EHIC or GHIC card; UK visitors use a GHIC. Everyone else pays, and travel insurance is worth having for the repatriation cover rather than the treatment. Mountain rescue is superb and is charged for; check your insurance covers it before hiking or skiing.
Ticks in forest and meadow up to about 1,500m, from spring to autumn.
The general rules — clinic timing, water, mosquitoes, insurance — are in travel health tips.
