I went there this afternoon at about 1:30. It was fairly busy, but quieter than it was back in January. Mostly Thais with a few older farangs, and I was surprised to see quite a few Thai children getting vaccinated too, there were none six months ago. All very efficient and bureaucratic as usual, I had Pfizer again.
They're closed tomorrow as it's a holiday for the King's birthday, I'm not sure about Friday which is a bridging day, but then next month they'll be doing the same thing just three days a week, on Wednesday, Thursday and Friday. My yellow vaccine book was updated and stamped, so I'm all set to return to Blighty for five weeks come September.
It's entirely up to you, of course, if you want it, but as I'm in the seriously at-risk group due to age and medical conditions I was more than happy to get a second booster. And by my own experience, they're effective. The GF spent a weekend with me a few weeks after the first booster but came down with a fever as soon as she got back home. The next day she tested positive for Covid at work. It's inconceivable that I wasn't exposed to the virus during two days of eating, talking, drinking and sleeping together, yet I had no symptoms at all.
