A reader of my web site sent me the following information following an eczema reaction that her baby son got to the DPT vaccine: "Boostrix and Certiva use the Stainer's Culture Medium which contains casein hydrolysate but the Adacel doesn't." She found some information on the CDC web site and some on rxlist.com. If you have any personal experience with this, I'd love to hear it. For the time being, I've put a caution on my web site.
