I've had 2 x AZ jabs and 1 x Pfizer booster, here in Thailand. I wont be having any more. I've had covid once, but it was a very mild version, akin to a snotty nose & sore throat. I've only ever had one "bad" case of "the" flu which knocked me off my feet for two weeks back in the eighties but have never felt the need to get the "flu" jab. I'm not going to start now.
