To determine whether the whole cell pertussis vaccine was protective against the development of food allergy.
In the late 1990s the type of pertussis vaccine (against whooping cough) used in Australia was changed from a whole cell vaccine to an acellular vaccine. During this time period a rapid increase in the number of reported food allergy cases among children was also observed. This is a retrospective study looking at children diagnosed with food allergy and they type of vaccine they received. This study aims to see if whole cell vaccine was protective against the development of food allergy. If this older vaccine is found to be associated with protection against allergy this is likely to impact vaccine policy in Australia and around the world.
All cases and controls must be registered on ACIR as having had a first dose of any pertussis containing vaccine before age 16 weeks and during the period of time in which the transition between aP and wP vaccine occurred; birth dates within 1st January 1997 and 31st December 1999 depending on the jurisdiction. For NSW, VIC, QLD and WA birth cohort is from 1st June 1998 – 30th October 1999 and for SA, to 1st April 1997 – 30th April 1999.
Recruitment completed March 2018. Data collection completed March 2018.
