I didn't even see your thread - sorry!
I wasn't able to find out thimerosal content through the lot numbers, even when I contacted each pharma with the lot numbers. They claimed they didn't have that info. at their fingertips and I wasn't able to find any public database. I realize now that I could have just contacted the law firm handling my son's compensation claim b/c they would definitely know, but I didn't even think to contact them.
I, along with a rep from each of the pharma's, were able to determine the thimerosal content from info. like the year it was administered, what brands were available at the time and wound up using the package inserts pertaining to the specific vax.
For instance, we were able to determine the Hib doses (manufactured by Connaught) did not
contain any thimerosal by deducing they don't manufacturer that particular brand any longer. Connaught only made one brand at the time, so we were able to figure that one out. NOTE: Most of the Hib vaccines on the market did in fact contain 25 micrograms of thimerosal though.
I would not suggest using the mercury calculator on one of the anti-vax websites (can't recall which one). When I used it, it was completely inaccurate.
If your child received vaxes back in 1999, I don't believe there could have conceivably been expiration dates for 2005. That said, I also don't think your doc had completely thimerosal free vaxes in 1999. The recommendation was made in 1999 and since there was no recall, ped's were able to use up what they had on the shelves. Besides, just because a recommendation was made in 1999 doesn't mean they immediately started producing thimerosal free vaccines. I find it hard to believe your ped had only TF vaccines on their shelves in 1999.
Here are the vaxes my son received in late 1997, 1998 and 1999 which contained thimerosal:
DTaP (4 doses - 25 micrograms each dose) ***I think all DTaP's at the time contained full strength thimerosal
Hep (3 doses - 12.5 micrograms each dose) ***I think all Hep B's at the time contained thimerosal. Not sure if some contained 25 micrograms.
