I signed up on Expatvac; and, about 3 months ago the same people came around to sign up everyone in the housing area. They had a round of vaccination (Sinopham) about 2 weeks ago; but, when I went there I was told sorry not your turn. Truthfully, I have no idea if the notification is linked to Expatvac; however, there was another guy from Sisaket who said he was also notified the same day (notification was the same way). In both cases they said Phizer would be used.
