Summary
The Bacillus Calmette-Guerin (BCG) vaccination coverage in Düzce, Turkey, reached 94% among 8th-grade students. Higher BCG administration correlated with fewer children per health worker, indicating resource impact on tuberculosis prevention.
Area of Science:
- Public Health
- Vaccinology
- Epidemiology
Background:
- The Bacillus Calmette-Guerin (BCG) vaccine is crucial for tuberculosis prevention, especially in high-risk developing countries.
- Turkey implemented a general BCG vaccination program in 1997.
- Evaluating vaccination status and program factors is essential for public health strategies.
Purpose of the Study:
- To assess the BCG vaccination status in Düzce, Turkey.
- To identify factors influencing the BCG vaccination program's effectiveness.
- To analyze the correlation between BCG coverage and health resource availability.
Main Methods:
- BCG screening conducted on 1100 8th-grade students across Düzce.
- Vaccination status determined by the presence and number of BCG scars.
- Statistical analysis to identify correlations between vaccination ratios and health personnel workload.
Main Results:
- BCG vaccination coverage was high, with 94% of students having at least one BCG scar.
- A significant negative correlation (r=-0.771, p=0.025) was found between BCG administration ratio and the number of children under 15 per health personnel.
- Variations in BCG vaccination status across different regions in Turkey were noted.
Conclusions:
- High BCG vaccination coverage was achieved in Düzce.
- Health personnel workload is a significant factor affecting BCG vaccination rates.
- Regional disparities in BCG vaccination warrant further investigation and targeted interventions.
