Three vaccination information leaflets (VIL) were evaluated in the province of Québec in 2002-2003 to examine their use by vaccinators (nurses and physicians), and their success in reaching parents of infants and toddlers. Data were collected from vaccinators and parents by postal survey. Reception of all of the VIL was higher among nurses (98%) than among physicians (39%). Only 14% of parents were familiar with all the VIL. Vaccinators who used the VIL, and the parents who were familiar with them, were satisfied with their presentation, clarity, quantity of information, pertinence and credibility. While the information leaflets were useful for vaccinators, few parents were reached, limiting the impact of this method of promotion.
