Sorry I haven't provided this earlier - going through a major pregnancy lazy arse phase!
The 5 in 1 vaccine over here is called PENTACEL and is made by Aventis.
Preservative is 2-phenoxyethanol, the main ingredient in Canadian anti-freeze.
The new preservative replaced Thimerosal AFTER the drug license was granted because Thimerosal interfered with the new inactivated Polio vaccine.
Adverse reactions in the first 72 hours are down but up after 10-12 days.
The web site below says that parents are finding it hard to get docotors to report adverse events.
This is the only web site I checked.
