Sources of parental knowledge about the safety of vaccinations in Poland.

There has been a recent increase in the number of parents refusing vaccination for their children in many European countries, including Poland. This observation necessitates the need to understand parental knowledge in regard to mandatory vaccination of children in these countries. A cross-sectional survey was conducted in 2016 on 1239 parents or legal guardians of preschool and school children in the Silesian Voivodship (Poland) to evaluate their hesitancy in acquiescing to their children mandatory immunization and the relation to this habit in regard to the use of informational sources on children vaccination system in Poland. Medical doctors often provide the basic source of information about vaccination to parents. About one-third (29%) of the respondents from the survey deemed the qualification system for vaccination as either inadequate or bad. 16.9% of the respondents surveyed declared that information received from physicians regarding vaccinations were either incomplete or unconvincing. Results of multivariable analyses confirmed that respondents are less likely to seek information about mandatory vaccinations from medical professionals and more often to misjudged vaccination's qualification system. Participants who used less informative sources (e.g. leaflets) and those with a lower level of education were more likely to avoid vaccination. Greater emphasis on the quality of information provided by medical professionals is crucial in order to avoid doubts about vaccination and to create proper attitudes and adherence to vaccination schedules.
