The study titled, The Immature Infant Liver: Cytochrome P450 Enzymes and their Relevance to Vaccine Safety and SIDS Research, was just published in the International Journal of Medical Sciences.
This comprehensive paper indicates that many infants can not safely tolerate routine vaccination schedules. By integrating pharmacogenetics, toxicology, and epidemiological evidence—including a detailed review of cytochrome P450 enzyme maturation, genetic polymorphisms, vaccine excipient toxicity, and post-vaccination death timing from VAERS—the authors show that underdeveloped liver enzyme systems may leave certain infants unable to detoxify vaccine components. The result is a biologically plausible mechanism linking early-life vaccination to sudden infant death, particularly in those with genetic or developmental vulnerabilities.
