Xibiao Ye, Shengjie Zhang, Marie Paul Nisingizwe and 8 others
PMID 41562601WHAT IT FOUND
Adults with intellectual disability in British Columbia were less likely to be infected, but if infected were more likely to be hospitalised, admitted to ICU or die.
Vaccination was linked to lower infection risk.
Key findings
01Adults receiving intellectual disability supports had a lower adjusted risk of SARS-CoV-2 infection than matched adults without intellectual disability.
02Vaccination was associated with a lower infection risk, and the association was stronger in adults with intellectual disability.
03Infected adults with intellectual disability were more likely to be hospitalised, admitted to ICU or die than infected adults without intellectual disability.

What it does not show
Only adults registered for community living supports were counted as having intellectual disability, so people with intellectual disability who were not registered may have been missed. The study did not examine specific intellectual disabilities such as Down syndrome. The sample was too small for meaningful stratified analysis by residence type, and too small for vaccination-stratified analysis of ICU admission and death. The study is observational, so lower infection risk may reflect other pandemic measures and living circumstances, not vaccination alone.
Declared interests
The authors received no specific funding and declared no conflicts of interest.
The easy way to misread this
Do not conclude that vaccination alone caused the lower infection risk. The study is observational, and adults receiving intellectual disability supports also had targeted access to vaccines, distancing, masking and other supports.
