The best source I've found for current Covid information for foreign countries is on the web site of the U.S. embassy in that country. For example Austria: https://at.usembassy.gov/covid-19-information/
I have trips planned to Canada and Austria in 2022. I'll be watching the sites. Canada is easy to get information. Other countries vary a lot, and several inside the EU have their own version of regulations. Do not expect consistency. Expect things to change as time goes on and this virus runs its course.
To carry and protect the vax card I use a pass holder, the 4" x 3" clear plastic holder for office passes, ID cards, etc. with a lanyard or pocket clip.
