Some loose-ish estimates, but some staggering figures in there.
16% of the world bought 70% of the vaccines. What force on earth could stop them? None, so we needed the massive supply increases, which were effectively banned.
What fraction of all vaccines were wasted?
- by excessive dosing. No sign of the dosing regimes changing despite strong evidence. 50-75%?**
- by bad needle design. 10-30% more.
Also includes some good links and references. And honest disclaimer from the author:
Note: I'm not a engineer, I'm not an economist, I'm not a pharmacologist, I'm not an epidemiologist. There will be something wrong with the above, no doubt in misunderstanding the nature of vaccine engineering bottlenecks.
