I just picked up my "Covid-19 Vaccine Certificate" (the little yellow book), for which i applied over 2 weeks ago.
They moved the pickup point from the 3rd floor in the main building, to far behind the hospital, behind the place where they have this chinese medicine and massage area (called "room25").
From the mainbuilding turn right at the beachside, as if you were driving out of the area, following the oneway-system (only about 50m).
Just before the road turns right again (away from the beach) drive straight, along the beach, until you reach the small river, which flows into the sea there.
There´s the "Traditional and Alternative Medicine Department", where they hand out the vaccine books now.
Don´t know if this is permanent, but it looks like.
