There's a bit near the end that really made me chuckle:
"This illogical removal of thiomersal from vaccines makes it nearly impossible to have multi-use vials, so every vaccine has to be in a single-use prefilled syringe, which has rapidly driven up the costs of vaccines.

That was an awesome move on their part."
