evidence: CLAIM: A packaging insert provided with the diphtheria, tetanus and pertussis vaccine shows it causes sudden infant death syndrome, or SIDS. AP’S ASSESSMENT: Missing context. The Centers for Disease Control and Prevention says multiple studies over decades have found no causal link between childhood immunizations and SIDS. At least one federally approved vaccine for diphtheria, tetanus and pertussis, or DTaP, does list SIDS among a host of other potential adverse reactions on its packaging insert. But the drug maker and experts say the list includes voluntary reports of adverse medical events experienced by people after receiving the vaccine, which have not all been proven to be correlated to the immunization. [...] The package insert for Infanrix, a DTaP vaccine made by GlaxoSmithKline, lists SIDS among a range of adverse effects, including respiratory illnesses and immune system and nervous system disorders.
