Ehh, free routine childhood vaccinations in New Zealand are supposedly universal and yet mysteriously kids in poorer areas, especially more rural ones, are less likely to actually end up having had them. (You've still got to get the kids to the doctor after all. Even if you do it at school... poorer kids are more likely to miss school for various reasons... like already being sick.) So it does still need to be explicitly controlled for.
But the conclusion seems both interesting and plausible anyway. Illness weakens your immune system - some illnesses more so than others.
