Most of the uproar is over the MMR vaccine that is given at either 12 months or 15 months, depending on your provider's preference. My daughter got the MMR vaccine at 15 months.
First, I do not believe that MMR causes austism-like symptoms in otherwise healthy children. The original study that "linked" autism to MMR has been renounced by the original researchers. Further, it is worth noting that you very likely received MMR as a child with no side effects.
However, many parents choose to either delay the vaccine or to break the vaccine up into its component Measles, Mumps and Rubella, using separate vaccines and spacing them out further.
Dr. Sears has a new book out the Vaccine Book from which many people use the delayed or selective vaccination schedule. I picked it up at the library and read through it before the 1 year vaccinations. I chose to skip Hep A until 2 years.
