We tried to get vaccinated in Albania, Poland, and Germany, with no success. The reasons were varied. Even by the time we left Albania on June 10th, they were vaccinating citizens only and unless in specified groups you had to be over 60 (we are 59). Poland was simply confusing, and there were language issues, and we ran out of time there trying to figure out their system. We didn't try very hard in Germany, but it seemed they were still intent on vaccinating only their own citizens.
Here in Netherlands, 90% of native Dutch speakers can also speak English. And many official government websites also have English versions so you don't have to rely on Google Translate. So when I read that there is a procedure to follow for foreigners on Dutch soil to get vaccinated, I started looking further into it.
