A wolf attack, especially on an adult, is extremely rare and mostly associated with habituation and feeding from human sources or rabies (mainly non European). This is from

"While being aware of the potential risks associated with wolves it is also crucial to place this into
context. In Europe and North America we only found evidence for 12 attacks (with 14 victims),
of which 2 (both in North America) were fatal, across a period of 18 years. Considering that there
are close to 60.000 wolves in North America and 15.000 in Europe, all sharing space with hun-
dreds of millions of people it is apparent that the risks associated with a wolf attack are above
zero, but far too low to calculate."
However, if I am wild camping or hiking in an area with wolves I will carry a small pepper spray for peace of mind.
