Distribution Of The Factors Influencing Discontinuation Of Routine Immunisation Among Children Under Seven Years In Chennai - An Observational Study.

Abstract

Immunization is vital in protecting children from infectious diseases like tuberculosis, diphtheria, and measles. Despite its importance, gaps in vaccine coverage persist. This study aims to examine the factors influencing the discontinuation of routine childhood immunization and assess the association between vaccine discontinuation and various demographic and socio-economic factors among children in Chennai.

This observational study included 224 children under seven years from primary health centers in Chennai, conducted over 18 months. Among the participants, 54.5% were female and 45.5% male, with most living in urban areas (63.4%). Factors influencing immunization included proximity to health centres and birth order, but socioeconomic status and literacy showed no correlation. Significant barriers included lack of family support (26.3%), long travel distance (20.5%) and vaccine hesitancy (13.4%). This study highlights modifiable and non-modifiable factors influencing immunization rates, including maternal knowledge and family support. Interventions addressing these barriers are crucial for improving immunization coverage in children.
