Insights
This study assessed immunization coverage in Bihar, finding that while corrected coverage is high, nearly 9% of children did not complete their vaccinations due to barriers like child unavailability and illness.
Area of Science:
- Public Health
- Pediatrics
- Epidemiology
Background:
- Immunization prevents millions of child deaths annually, with vaccines averting 20 million premature deaths and 500 million disease cases globally.
- Despite progress, routine vaccine coverage remains a challenge for underserved and vulnerable populations, necessitating periodic evaluation and improvement strategies in Bihar.
Purpose of the Study:
- To determine the vaccination coverage rates across different Blocks within the study area in Bihar.
- To identify factors affecting immunization status among children aged 12-23 months in low-performing blocks.
Main Methods:
- A community-based cross-sectional study was conducted in 59 low-performing blocks of Bihar from January to March 2019.
- The study included children aged 12-23 months residing in selected villages within these blocks.
Main Results:
- The corrected full immunization coverage (FIC) was found to be 90.85%.
- Approximately 8.8% of children initiated vaccination but did not complete it, while others were completely left out.
- The primary reasons cited for incomplete immunization were child's unavailability on vaccination day and child's sickness.
Conclusions:
- Overall immunization coverage in Bihar is lower than the national average reported by NFHS-4.
- The study highlights a higher rate of corrected immunization coverage, suggesting potential for improvement in program implementation.
Introduction:
Immunization is one of the most cost-effective measures in public health to date, preventing at an approximately 2 to 3 million fatalities in young children every year. As per recent World Health Organisation (WHO) bulletin, these lifesaving vaccines have been successfully averted around 20 million premature deaths and 500 million disease cases. Inspite of this progress the routine vaccine coverage is slow to rise as challenges still live for the underserved, inaccessible and vulnerable children. It is therefore essential to evaluate the coverage of immunization at periodic intervals and to take the required measures to enhance the vaccination status in the State Bihar.
Aims And Objective:
This study aims to find out the vaccination coverage in different Blocks of study area.
Material And Methods:
The study was community based cross sectional study which was conducted between January to March 2019 in the selected villages of 59 low performing blocks of Bihar. The study subjects were all the children aged 12-23 month old from selected low performing blocks of the Bihar. Results-Corrected FIC of the study was 90.85%. Close to nine percent (8.8%) children thou have started vaccination could not able to complete it. Rest of the beneficiaries are completely left out. The most common reason for incomplete immunization was unavailability of child on the day of vaccination followed by sickness of the child.
Conclusion:
The overall Immunization coverage of Bihar is less than the National Immunization coverage as per NFHS-4. This study shows higher rate of immunization as far as Corrected Immunization Coverage is concerned.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
