Okay. And what specific number of quality adjusted life years would a vaccination program need to promise to save across the globe before you personally are willing to take it?
Do you feel comfortable acknowledging that this metric in isolation could result in trading years across age demographics? To what degree does it matter if we take 1 year of life from a child and give it to a middle aged person, doing exactly that would be fairly neutral according to QALY.
Taking 1 year of life from person a and moving it to person b is fairly neutral, yes. If, without intervention, both of them were likely to live to 80, now one of them will live to 79 and the other to 81.
That probably doesn’t matter much to either a child or a middle aged person, to be honest, since neither of them has much idea of exactly how many years they have left.
It probably matters quite a lot more to a 78 year old, though.
A vaccine is a public health measure aimed at reducing disease spread through the population.
If you want kids to go to preschools, and not be little disease vectors transmitting infection between households, you should be looking for ways to avoid them acquiring the infection even if the disease has no ill effects on them personally.
Having their parents or grandparents hospitalized are also negative outcomes for a child.
