evidence: The claim: Insert in a DTaP vaccine package proves it causes SIDS [...] Cherie Duvall-Jones, an FDA spokesperson, told USA TODAY in an email that the agency is aware of a "very low" number of reports of SIDS after DTaP vaccination in the Vaccine Adverse Event Reporting System (VAERS). She said the agency has not seen any safety concerns or a causal link. [...] A second paper looked directly at SIDS rates after DTaP vaccination in a population of more than 120,000 children over 11 years and found no increased risk of SIDS.
