Avram.
This is distasteful for me to have to say this. But I think health is right in this one point.
Although thimerosal was removed from ophthalmic solutions with very good reason. It seems the same isn’t true regarding its removal from vaccines.
It was found to be very effective and very safe (few minor potential reactions).
Seems it was removed under pressure from those claiming it was probably the causative factor in autism. And because it contains mercury.
It is ethylmercury as opposed to elemental mercury or methylmercury(the bad mercuries).
Em is rapidly metabolized and excreted. It is not retained as is methylmercury.
I don’t know the whole cheshbon, but it seems the main impetus to remove it was nonscientific pressure.
