Recently I wrote about a study, Immunization uptake in younger siblings of children with autism spectrum disorder, in which it appeared they had a comparison of immunized vs. non-immunized. I contacted the authors for clarification and found that “non immunized” meant the lack of the two combination vaccines. They did not specifically ask for or collect full immunization data on all children in the study.

Thanks for the clarification, I had wondered about that.
