Moderna offers (rego and pre-payment 3300 baht) now avlble from Medpark. Due not in Ocyober, but rather Q1-Q2 next year. So that could be as late as June 2022. Unless you're under 60, there's lots of Pfizer jabs on offer in TH now, I had three potential appointments for the 1st jab, and chose a hospital in Bkk for it. Excellent service, very professional, social distancing, all orderly.
