I am going to Vienna in April and am wondering what vaccines we need. We already have Hepatitis B, measles, annual flu, and the chickenpox vaccine. We also have the tetanus vaccine. Do we need any more vaccines?
The CDC has this site with general recommendations for every country.
No special vaccines needed for Austria, or Europe in general. Just like at home you should be up to date on your regular things and get a flu shot. Also DTAP often requires adult boosters. All this is the same as if you stayed in the US - it's not Europe specific.
Just be careful of ticks in the woods and fields.
As Nigel said about ticks. I did get Lyme disease in Western Europe. Even the Ice Man had it 5,000 years ago. https://news.nationalgeographic.com/news/2013/10/131016-otzi-ice-man-mummy-five-facts/#/72519.jpg
It is good for everyone to get the Hepatitis A vaccine, even if they never travel. It is part of the routine immunizations that younger people get. There is currently an "outbreak" in two northern Alabama counties, although so far it is limited to people in high risk groups, and anyone can get it if they come in contact with contaminated food or other items.
When I asked for Hepatitis A last year I was given a combination Hep A/Hep B vaccine. It was two innoculations 6 months apart. The first one does confer some protection during the interim period.
Your established healthcare provider can tell you if you are up to date on routine vaccines.
Your provider Is privy to your health history. This will answer your individual needs. Enjoy your stay.
It would be a good idea to check with your health care provider or a travel medicine clinic to ensure that your routine vaccinations* are up-to-date (such as Tetanus, Diptheria, Pertussis, Measles, Mumps, Rubella, Polio, Influenza). According to one site that I checked, "Due to ongoing outbreaks in many European countries, travellers should ensure they are up-to-date with their Measles vaccinations prior to travel."
In addition to Lyme disease mentioned earlier, West Nile Virus may also be a problem in some areas. There are no vaccines for those, so mosquito repellent may be prudent. Tick Borne Encephalitis is also a concern in some areas.
Austria has a robust health care system and people in Austria are overall some of the healthiest in the world. Communicable and tropical diseases are not an issue. Just make sure you are up to date on your standard immunizations. If you plan to spend significant time in the woods hiking, then be mindful of the ticks.
