Ignoring the forest and the trees: Vaccine antigen study is overmatched

Abstract

Although the dataset of DeStefano et al1 has been cited as proving that vaccination is not related to autism, it actually matches out antigen variation. This is a fact that those familiar with the concept of overmatching can readily perceive.2 The birth years for the study are 1994-1999. In 1996, varicella was added to the vaccine schedule. For children born in 1998, rotavirus was given. In 1997, whole-cell diphtheria, tetanus, pertussis (DTP) vaccine was replaced with diphtheria, tetanus, acellular pertussis (DTaP), introducing a huge change in the amount of antigens.
