Very good point about mercury. What are people supposed to think? "Mercury is so bad I'm barely allowed to purchase or handle it, but then I'm supposed to then inject it into my baby?" Yes there's a lot of nuance here, and a lot of cost/benefit analysis around the risk of a tiny amount of mercury (in excretable compound form) vs. the risk of nasty diseases. But it becomes harder to communicate that nuance and be believed when you've just been telling people to eat margarine (artery plaque) for 50 years.
