Timeliness vaccination of measles containing vaccine and barriers to vaccination among migrant children in East China.

Hu Y, Li Q, Luo S, Lou L, Qi X, Xie S - PLoS ONE (2013)

Bottom Line: Being unaware of the necessity for vaccination and its schedule, misunderstanding of side-effect of vaccine, and child being sick during the recommended vaccination period were significant preventive factors for both MCV1 and MCV2 vaccination.Having multiple children, mother's education level, household income and children with working mothers were significantly associated with delayed or missing MCV1 immunization.To avoid future outbreaks, it is crucial to attain high coverage levels by timely vaccination, thus, accurate information should be delivered and a systematic approach should be targeted to high-risk groups.

ABSTRACT

Background: The reported coverage rates of first and second doses of measles containing vaccine (MCV) are almost 95% in China, while measles cases are constantly being reported. This study evaluated the vaccine coverage, timeliness, and barriers to immunization of MCV1 and MCV2 in children aged from 8-48 months.

Methods: We assessed 718 children aged 8-48 months, of which 499 children aged 18-48 months in September 2011. Face to face interviews were administered with children's mothers to estimate MCV1 and MCV2 coverage rate, its timeliness and barriers to vaccine uptake.

Results: The coverage rates were 76.9% for MCV1 and 44.7% for MCV2 in average. Only 47.5% of surveyed children received the MCV1 timely, which postpone vaccination by up to one month beyond the stipulated age of 8 months. Even if coverage thus improves with time, postponed vaccination adds to the pool of unprotected children in the population. Being unaware of the necessity for vaccination and its schedule, misunderstanding of side-effect of vaccine, and child being sick during the recommended vaccination period were significant preventive factors for both MCV1 and MCV2 vaccination. Having multiple children, mother's education level, household income and children with working mothers were significantly associated with delayed or missing MCV1 immunization.

Conclusions: To avoid future outbreaks, it is crucial to attain high coverage levels by timely vaccination, thus, accurate information should be delivered and a systematic approach should be targeted to high-risk groups.

Mentions: Analysis of the PMT model revealed that for MCV1, the average score of barriers of vaccination was significantly higher in the unvaccinated group than that in the delayed and timely groups, while the average scores for perception of susceptibility and knowledge were significantly lower in the unvaccinated group than those in the delayed and timely groups. For MCV2, the average score of barriers was significantly higher in unvaccinated group than that in vaccinated group, while the average score of knowledge was significantly lower in unvaccinated group than that in vaccinated group. Perception of severity and benefit were not significantly associated with missed or delayed MCV doses(Figure 2).
