Objective: This study aimed to explore the impact of adding new vaccines on schedule adherence and parental opinion of multiple injections.
Method: A descriptive cross-sectional study by self-administered questionnaire mailed to a stratified random sample of each of two cohorts of children drawn from the Montérégie Birth Register: the 2002-2003 cohort (old vaccination schedule) and the 2004-2005 cohort (new schedule). Two surveys were done: Survey 1 (fall 2005-winter 2006) questioned parents whose address could be validated by Canada411.ca; Survey 2 (fall 2006) surveyed parents whose address was validated by the Quebec health insurance board (RAMQ). Incomplete or missing vaccine data were completed by verifying the vaccinators' files.
Results: Analysis of schedule adherence by the Kaplan-Meier survival approach showed that the 2nd and 3rd doses of the DTaP-P-Hib vaccine were received late by the youngest children compared to the oldest (median number of days late: 2 days for the 2nd vaccine (p = 0.013) and 4 days for the 3rd vaccine (p < 0.001)). Many parents (76%) prefer 2 to 3 injections during a single visit, and 61% fear an increase in the risk of side effects.
Conclusion: Even if the evaluated lateness has only a small public health impact, parents must be reassured about the safety of multiple vaccines.
