Its just me, sorry GillT57 
But I look at something like this and think, well, how do they know? How much did they think they would lose to wastage? Is 1.7% actually quite good? Did they think they were going to use them in August but no-shows made it impossible to do that? Would it have cost far too much to repackage it all up and send it off somewhere else? Could the destination country actually have done something with it? Are there contractual issues that would prevent them giving vaccines to other countries?
Can't help it, sorry....
