You're right, it is an anecdote, but since you made a statement about what HCP do in general, one single anecdote to the contrary is enough to disprove your statement. It's called a counter example.
Ahhh…so we are playing logic games (lol)? I will remove the "in general" and then your single anecdote to the contrary will not disprove the statement.
I will look for more stats, but saying that 90% of flu vaccine contains thimerosal is not at all the same as saying 90% of women and children who get the vaccine get the thimerosal version, I'm sure you know that though, being a fellow math lover.
I do…but 90% is a large number. I imagine some are being used for children and pregnant women. It is possible the thimerosal free version is being saved for children and pregnant mothers, but without numbers, we have no proof. You have one hunch, and I have another, and that is it.
