Can aspirin induce reyes syndrome with a child that recently was given the varicella vaccine?

Doubt anyone knows. We have not recomended the use of Aspirin products to any child under 16 in 20+ years(except for rare use in kawasaki disease or jra).Why any parent would use it now after any vaccine is puzzeling. Only a fraction of flua or chichenpox sufferers that were given Aspirin developed reyes so the risk would be low but why ever give it to a kid unless it was the last possible med available.
