Secrets to success: a qualitative study of perceptions of childhood immunisations in a highly immunised population.

Tarrant, Marie; Thomson, Neil

AIM The aim of this study was to explore childhood immunisations with a sample of parents from a population where children have high vaccination coverage and to identify factors which might encourage uptake in other populations. METHODS This research was conducted as part of a larger study on childhood immunisations in Hong Kong. In-depth interviews were conducted with a subsample of parents (n = 15) to further explore general perceptions and health beliefs about childhood immunisations. Interview data were analysed using content analysis techniques. RESULTS Three core themes emerged from the data: individual influences factors, family and social factors, and system factors. [Correction added after online publication 21/8/08: sentence corrected from "Four core themes emerged from the data: individual influences, family influences and system influences."] Parents readily admitted knowledge deficits concerning childhood vaccines but believed that the benefits of immunisation outweighed the risks. Family members and peers were a source of pro-immunisation advice and comprehensive public health programmes and mandatory vaccination requirements for school entry ensured that childhood immunisation recommendations were followed. CONCLUSIONS Overall, Hong Kong parents are highly supportive of immunisation programmes and insight gained from this study could prove helpful to providers trying to improve uptake rates among other populations.
