PURPOSE: The purpose of this study was to determine the reasons for non-vaccination and magnitude of missed opportunities for vaccination in children in a suburban town in India despite availability of free immunization against six vaccine-preventable diseases (VPD) under the Universal Immunization Program (UIP) launched in 1985.

METHODS: We conducted a cross sectional study of all children presenting to a Primary Health Clinic in B.K. Nagar, Bangalore, from 5-1-2011 to 5-31-2011. We interviewed 50 mothers of children under 16 years of age regarding vaccination with BCG, DTP, OPV, and measles under the UIP. Our questionnaire focused on demographics, immunization status (card or mother’s report), reasons for missed vaccinations, beliefs of parents toward immunization, awareness of available optional immunizations, and adverse effects. Children were considered fully immunized if they received BCG, DPT, OPV, and measles, as unimmunized if they received none of these vaccines, and partially immunized if immunization was not complete.

RESULTS: Of the 50 children enrolled during the study period, 40 (80%) received complete immunization while 10 (20%) received partial immunization until the age of 10 years. Between 10-16 years, however, 24 (48%) were unimmunized. 19 (40%) parents were unaware that tetanus toxoid (TT) boosters were required at ages 10 and 16 and never received instructions. 24 (48%) were unaware that TT boosters were required every 5 years. The parents themselves were unimmunized. All parents were aware of the need and importance of vaccination. Financial constraints prevented availing of optional immunizations in 84 % parents. No parents expressed concerns about adverse effects.

CONCLUSIONS: Although the UIP is able to achieve its objective of providing universal immunization coverage in BK Nagar until age 10 years, it is unable to maintain vaccination thereafter. Despite availability of vaccines and trained field personnel, the problem is ineffective social mobilization and parental unawareness of the schedules. There were no concerns about the need for or the quality of vaccines.

CLINICAL IMPLICATIONS: VPD can be significantly reduced by ensuring adequate surveillance, monitoring to detect unimmunized children, and education of parents regarding immunization shedules.
