PCC CNS Disord 2022;24(4):10.4088/PCC.21m02952 Clinical Summary Children with developmental delay and their siblings can be left vulnerable to vaccine-preventable illness when family vaccination behavior changes after a developmental diagnosis. This study addresses a clinically important question beyond autism spectrum disorder: whether lower vaccine uptake extends across families of children with developmental disabilities seen in child development centers. FAQ Did this study find lower vaccination rates in children with developmental delay and their younger siblings? 9 questions
Key Takeaways The comparison group in this study was within-family: typically developing elder siblings had higher complete vaccination (85%) and MMR uptake (86%) than both probands and younger siblings, which points to a change in family vaccination behavior rather than a background community rate. 5 takeaways Clinical Guide How should clinicians review vaccination status in families of children with developmental delay to identify underimmunization across siblings? 5 steps
