[Excerpts from transcript of video] Is there a connection between vaccines and autism? Thousands of families with autistic kids think there is. But the Centers for Disease Control has always maintained that no research supports a link. Now one famous pediatrician, who has written a book about vaccines, charges the government's studies on vaccines are woefully inadequate. Dr. Bob Sears is the author of The Vaccine Book: Making the Right Decision for Your Child: [Q]: The government says they have studied vaccines and they do not cause autism. But has the government ever studied the amount of vaccines that our children get in one sitting? [Sears]: There is a CDC report that says that ... simultaneous vaccination has not been completely studied for safety and that's what we're worried about. Babies get as many as six or seven vaccines altogether ... and the CDC is admitting that they aren't always researched that way. The prime example is the flu vaccine. They've researched the flu vaccine in great detail when given alone, but the CDC has never researched it when given in conjunction with all the other shots. I think the CDC is just assuming that they are safe. But I want to know that these large combinations are safe. And what I do as a pediatrician, is I spread the vaccines out. I give no more than two vaccines at a time to any babies in my office. It takes longer to vaccinate them that way but I think it's a safer way to go.
