Since I registered I have been given 3 appointments for Bangkok hospitals, 1 for Sriracha and another 1 for Pattaya.
I am over sixty and live in Chonburi City.
By the time the first hospital contacted me I had already had my first jab of Astrazenac (via the BTCC).
I cancelled the first appointment and did my best to inform them that I didn't need an appointment anymore, but the appointments kept coming. I was offered Astrazenac or Pfizer vaccine as a choice.
They have stopped sending me appointments now.
So in my case the website worked very well.
