The current study, released by Archives of Disease in Childhood, re–examined Wakefield's findings by testing 100 autistic children, 52 learning challenged kids, and 90 children who were developing normally. Every child had received the MMR vaccination, but not everyone got both doses.
Dr. Gillian Baird, the pediatrician on the study, said:
"The researchers took blood samples from the children and found no abnormal immune response in any of them marked by higher antibody levels or presence of a measles virus still left in the body from the shot."
A researcher at Britain's Health Protection Agency, David Brown, worked on the study and said,
This study really supports the view these are safe vaccines. The evidence is now so solid there really isn't a need for further studies here.
