On-time measles and pneumococcal vaccination of Shanghai children: The impact of individual- and neighborhood-level factors

Measles-containing vaccines (MCV) and pneumococcal vaccines (PCV) can prevent a large proportion of infant deaths and are recommended by international organizations for inclusion in pediatric immunization schedules. In China, MCV but not PCV, is publically funded and access to vaccination may be limited among non-locals, who are rural migrants to cities. In this study, we estimate the proportion of Shanghai children with on-time MCV and PCV administration; compare vaccination in non-locals versus locals; and assess the impact of township-level characteristics on vaccination outcomes.

Methods. Data from children in the Shanghai Immunization Program Information System were linked to township-level data from the 2010 China Census. We used generalized estimating equations with logistic regression models to assess the impact of residency and township-level predictors on on-time MCV and PCV administration.

Results. Non-locals had lower vaccination levels than locals. Compared with locals, non-locals had 0.50
