The only thing that hasn't seemed to change in the last 13 years is the number of years it takes to diagnose a child with autism.
"They're usually diagnosed when they are 3 years old," Pathologist Stephanie Wright said.
But according to recent studies, from the Centers for Disease Control and Prevention (CDC), autism can be detected in children as early as 2 years old.
Carrie Albert's son is now 15. He was diagnosed severely autistic when he was 4. She said she's well aware that some parents and even some doctors link vaccinations to autism, but she's not one of them.
"I also work within the school system," Albert said. "So if had to do it all over again, I would still have both of my children vaccinated."
Albert said her son showed signs of autism even before he was vaccinated as a child.
"The flapping, the noise making of certain types," Albert said. "He would look at certain objects for a long time."
The specific vaccine ingredient in question is Thimerosal. However in 2001 it was removed from all childhood vaccines, and within those 13 years the number of children diagnosed with autism has almost doubled.
The CDC recently reported it supports the Institute of Medicine's conclusion that "there is no relationship between vaccines containing Thimerosal and autism rates in children."
"Right now we see it as it's something they're born with," Wright said. "And they just need as much help as we can give them."
