I’m not an anti-vaxxer by any stretch of the imagination but the thing being so blatantly overlooked here is that it’s a very slippery slope once you start mandating stuff like this. So Airlines require a vaccine for travel, what’s to stop people being asked to show proof of vaccination before stepping on the London Underground? Or taking their seat in a packed theatre? Or doing their shopping in a busy supermarket? What’s the difference here? It’s hard to maintain the stance that a vaccine isn’t compulsory when potentially every activity in life requires it.
