[Risk factors for delayed or missed measles vaccination in young children]

Because of low measles vaccine coverage rates, measles outbreaks have been observed several times during recent years in Germany. The aim of this study is to identify parents' attitudes and beliefs towards immunisations and socio-economic factors which are associated with delayed or missed first measles vaccination in young children. We used data from a representative German-wide immunisation survey on 2116 children born between 1 January 2002 and December 2004 by collecting precise vaccination information from vaccination cards. The influence of socio-economic determinants and parental attitudes towards immunisations on the timing of the first measles dose was analysed by using multivariable Cox regression. Of these children 46.8% (95% CI: 44.5-49.1) received their first measles dose according to the recommendations of the standing committee on vaccination (STIKO) by month 15. In multivariable analysis, fathers aged 28-33 years and birth order as well as parents' belief in homeopathy and other parental attitudes indicating lack of knowledge about the importance of vaccinations significantly influenced an early immunisation. Not general opposition, but insufficient parental knowledge about the harmfulness of measles infection seemed to be responsible for the low measles vaccination rates.
