I'm sure we all now know that the U.S. federal court pulled the theory that vaccines cause autism. Now there's more evidence that vaccines do not cause autism. According to a new study author, Dr. Frank DeStefano, director of the immunization safety office at the U.S. Centers for Disease Control and Prevention infants exposed to the highest levels of thimerosal, a mercury-laden preservative that used to be found in many vaccines, were no more likely to develop autism than infants exposed to only a little thimerosal. The study offers more piece of mind to parents who are still scared that vaccines may cause autism. Thimerosal has been used as a vaccine preservative for decades (since the 1930s) but concerns about it only popped up in 1999 when the FDA decided that thimerosal-containing vaccines meant that infants may be exposed to too much mercury. Thimerosal, in the past, was used in various vaccines such as hepatitis B, Hib (Haemophilus influenzae type B) and DTP (diphtheria, tetanus, pertussis) vaccines and others. As of today, thimerosal has been removed from vaccines meant for young children and babies, except for the inactivated seasonal flu vaccine. The new study looked at medical records of 256 children with an autism spectrum disorder and 752 children matched by birth year who did not have autism. Information about vaccines that the children received were also studied to determine how much thimerosal they were likely exposed to. Children who got the highest 10% of thimerosal exposure were no more likely to have autism than children in the lowest 10% of exposure. Although, I'm a vaccine advocate, I do think that before you get your child vaccinated, you should look into all the pros and cons. Here's some more tips: The new study was released online Sept. 13 in advance of publication in the October print issue of Pediatrics.
