This study investigates the immunization status of children among the Bhunjia tribe in Chhattisgarh, India, highlighting the factors influencing vaccination coverage in this marginalized community. The primary aim was to assess the immunization rates and identify barriers affecting vaccine uptake. Using a cross-sectional survey methodology, data were collected from 206 mothers of children aged 11 to 59 months. The findings revealed that only 33.01% of children were fully immunized against six vaccine-preventable diseases, with notable coverage disparities: BCG vaccination was received by 86.41% of children, while measles coverage was only 34.95%. A significant barrier identified was the lack of awareness, with 43.24% of mothers unaware of the need for immunization. Additionally, logistical challenges such as distance to healthcare facilities contributed to low vaccination rates. The analysis also indicated that the availability of approachable roads was significantly associated with improved immunization status, emphasizing the importance of health infrastructure in tribal areas. The results underscore the urgent need for targeted public health interventions to raise awareness and improve accessibility to immunization services. By addressing the unique challenges faced by the Bhunjia tribe, healthcare initiatives can enhance vaccination coverage and ultimately contribute to better child health outcomes in this and similar communities. Overall, this study highlights the critical role of community engagement and infrastructure development in promoting immunization among vulnerable populations.
