He’s 4th?! Why so many boosters? Some 16 hours later and only a slightly sore arm as side effect I’ll take that.
He lives in Abu Dhabi, you really don't have a choice. His family had the jab early and at the time they could only have the Chinese version which wasn't popular. ( no side effects by the way )
Now that Pfizer jab pretty establish their government pretty strick with covid. It's basically have it done or leave the county. If they say jump, over there you pretty much job as they can be very difficult to put it mildly.
