Data collection
Data was collected on the dispensing of the dTcaP booster vaccine by pharmacies and pro-pharmacies within 12 months that the information by the CPAM had been disseminated. Outcomes included the dTcaP booster vaccine delivery (which was assessed using the Club Inter Pharmaceutic (CIP) codes corresponding to the vaccine in the CPAM database) and a consultation with a GP at least once within 12 months after the start of the awareness campaign for those who had already received the dTcaP booster vaccine. A GP consultation was an endpoint because the French national health insurance running the awareness campaign suggested that patients consult with their GP.
