evidence: DTaP vaccine isn’t associated with sudden infant death syndrome, whooping cough vaccine led to historic decline in cases [...] Factually inaccurate: Studies have found no association between the DTaP vaccine and sudden infant death syndrome (SIDS). Childhood vaccination isn’t a risk factor for SIDS. An Instagram reel posted in March 2024 suggested that the whooping cough vaccine was never needed, since whooping cough deaths had plummeted before the vaccine was available. It also implied that the DTaP vaccine is dangerous and associated with sudden infant death syndrome.
