This has been double posted on the Vaccination thread. But I have a 3 month old that will be going for his well baby visit. He'll be getting his first shot. I think I've decided to give the Deptacel/DTaP shot only at this point. However, our doc uses the Infanrix brand which has double the amount of aluminum and uses cow tissue extract. They suggested I contact the company to find out how to get Deptacel. I went to the Sanofi Pastuer website and sent an e-mail, but thought someone here may have insight into how to go about getting the brand of vaccine you choose, but the pedi doesn't use. HELP!
