Hard to find exactly why, but there is this fragment:
Vaccine-makers have also since introduced newer versions that are adapted to the latest coronavirus variants, making older jabs obsolete and more likely to be discarded.
Also vaccines don't last forever, and at some point these ones would become risky enough that it wouldn't be advisable to give them to those who didn't get any (original version or recent).
This headline speaks to the logistics and distribution problems, as well as things like patents and profit.
There will be other pandemics in the future, and we need to do better.
Honestly, except for the ridiculous levels of vaccine hesitancy, I think the world gets a passing grade for this pandemic. The response (from scientists not politicians) was fast and strong... and, for an emergency, the amount of waste wasn't unreasonable.
