Got a phone call yesterday (Monday), Phizer, 1st jab 2:30. Bring passport. This was in Chai Nat, not renowned as a large expat community. On arrival seated with 4 other expats, check height and weight then off to the vaccination area. Blood pressure check, then, after a short wait off to the jab area. After, back to a waiting area to see if there any early complications. 30 mins later. blood pressure test again and check if feeling OK, given the hospital hotline number if a problem arises later. Provided with a certificate which also details second jab – 20 Sept. So, the registration site worked, I am 67 with no underlying health problems. Happy Days!
