For those who may be interested here's a video taken yesterday ( credit Asian wish youtube channel) - of an Austrian guy going through the entire process of being vaccinated after being provided a first vaccine at the Bang Sue centre by their embassy. It shows the centre very busy with many farang in attendance it seems, with attempts at social distancing in place but perhaps not being very well policed ( compared to our local centres anyway). One valid point he made was that it took 3.5 hours in total and left him within 10 minutes of not making it back to Pattaya before curfew kicked in, so that's perhaps something to build into your plans if lucky enough to be called up I guess.
