I sent a message to the US Embassy in BKK 1 month ago after learning about the US donation. As a US citizen over the age of 60, I even offered to pay for 2 shots of the then pending Pfizer donation. I posted their reply to me and my response back to them in a previous forum thread on July 8. Basically, they told me I had to depend on the Thai gov't to get a decent vaccine. I have since been able to register for Moderna at a hospital in BKK but, for obvious reasons, have no confidence that I will ever receive the shots.
