From the study above:-
"In Australia, a rise in hospitalisations among infants coded as anaphylaxis to foods coincided with the replacement of whole-cell pertussis (wP) vaccine with subunit acellular pertussis (aP) vaccine on the national immunisation schedule in the late 1990s"

"Food allergy is not only important in its own right, it is also associated with eczema and with asthma (fourfold increased risk) in later childhood"
