Summary
Bacille Calmette-Guérin (BCG) immunisation coverage in Mozambique was assessed at 86.3% for newborns in 2011. Improved data recording is needed for accurate vaccination coverage assessment.
Area of Science:
- Public Health
- Vaccinology
- Epidemiology
Background:
- Official immunisation coverage reports in Mozambique's Maringue District were unreliable, exceeding 100%.
- This unreliability prompted an evaluation of Bacille Calmette-Guérin (BCG) immunisation coverage among newborns.
- The study focused on seven health units within the Maringue District, Sofala Province.
Purpose of the Study:
- To evaluate the actual immunisation coverage of BCG among newborns in 2011.
- To identify limitations in data collection and reporting for vaccination coverage.
- To recommend improvements in recording practices for more accurate assessments.
Main Methods:
- Data on live newborns in 2011 were obtained from maternal clinics.
- An estimate of home deliveries was included in the total newborn population.
- BCG vaccination records from 01/01/2011 to 30/06/2012 for children born in 2011 were abstracted.
Main Results:
- A total of 3,353 live newborns were recorded in 2011.
- 2,893 BCG vaccinations were administered.
- The calculated BCG vaccination coverage was 86.3%.
Conclusions:
- The study achieved an approximate BCG vaccination coverage estimate due to data limitations.
- Unavailability of adequate individual information hindered precise coverage calculation.
- Enhanced recording practices and data linkage are crucial for accurate vaccination coverage assessment.

Overview
01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
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.
