The US Govt. has refused to protect us because it doesn't want to be sued for creating generations of autistic and disabled or diseased citizens. So it continues to ensure that thimerosal etc. gets into toddlers by means of implementing more frequent flu shots with thimerosal, while agreeing to remove thimerosal from most other shots. How clever and uncaring. Pharm and US Govt/CDC,. etc. are and always have been bedfellows. Caviat emptor.
