Where do you get your date of 2003 from?
Thimerosol was beginning to be removed from many vaccines even before 2000 when the official recommendation came.
Here's some information I've posted before on these boards:
Here is a table which states when thimerosol was removed from the vaccines on the childhood schedule in the US which contained it (notice how many never had any in the first place).
Here's the recommended vaccination schedule in the USA from 2000 http://www.cdc.gov/mmwr/preview/mmwrhtml/mm4902a4.htm
Here's my matching of the two. Please correct me where I'm wrong, because to be honest from this list I'm confused why thimerosol was ever an issue.
Series in first 18 months (note this extends to 2001-2002 for these children some of whom were born at the end of 2000)
3 doses of Hep B - one version thimerosol free in 1999, the other licenses thimerosol free in March 2000.
4 doses Dtap - 2 types never had thimerosol, the third was licensed thimerosol free in March 2001
4 doses HiB - of kinds available in 2000 one never contained thimerosol, the other was licensed in thimerosol free version in 1999
3 doses IPV - never contained thimerosol
at ~12 months (so in 2001 or early 2002)
MMR - never contained thimerosol
Varicella - never contained thimerosol
Sure some doctors offices would have old vaccines in stock and would use them up until the expiry date (since there is no proof thimerosol at the levels in vaccines is of any danger to anyone), but any new vaccines purchased from 2001 onwards would have been completely thimerosol free. Children born in 2002 would have had on average very little exposure to thimerosol (if not zero).
Probably just small number statistics you're seeing in your child's school.
